Andrij “Andrew” Harasewych410,851It's been a pretty disappointing year for some of us, celestial sights wise. There have been the usual meteor showers (it was cloudy for me every time), the transit of Venus (also cloudy) and several eclipses (none were visible from my area). Luckily, we still have the Geminids left. They're generally considered to be one of the best and most reliable meteor showers of the year, so hopefully we'll get a good show. They will appear to radiate from the constellation of Gemini, and you could spot up to 120 meteors per hour. The moon will be new meaning that visibility should be very good. Although Dec 13th-14th is the peak, meteors will be visible for several days before and after that so don't forget to look up this week. As usual, if you get any good photographs/videos please send them our way!Geminid Meteor Shower2012-12-14 00:00:00161

We are all related : Strange as this sounds, this is the outcome of a scientific search for the human migration using genetic markers. As genetic mutations were observed, the rarer of these were passed down from father to son (Y-chromosomal) and from mother to daughter (mtDNA). Tracing these back led to one tree for men and another for women. And the male line and female line do not converge. Though we are all descended from what is called Y-chromosomal Adam and mtDNA Eve, they did not live at the same time. I'm assuming the other lines just died out. The surprising conclusion? We are all related. We are genetically related.

We are all related. We are genetically related.

Our common ancestors : Some 99% of the human genome is shuffled from one birth to the next. The Genographic Project traces the 1% of the genome which is not shuffled—mitochondrial DNA (mtDNA) through the maternal line and the Y-chromosome through the paternal. These jokers in the pack allow geneticists to work back to our common ancestors. Our mtDNA appears to coalesce in a single woman, who lived on the African savannah 150,000 years ago. Our Y-chromosome survives from a single man, who lived in the Rift Valley of Kenya or Tanzania 59,000 years ago. So Adam and Eve did exist—90,000 years apart. The discrepancy is because, unlike the biblical Adam and Eve, this couple only represent the last common Ancestors we can trace genetically.

African Roots : Different populations carry distinct genetic markers. Following the markers through the generations reveals a genetic tree on which today’s many diverse branches can be followed backward to their common African root. The markers still present in our genes allow us to chart ancient human migrations from Africa across the continents. Through these markers, we can see living evidence of an ancient trek to populate the globe.

How Neanderthal are you? : Everyone living outside of Africa today has a small amount of Neanderthal in them, carried as a living relic of these ancient encounters. A team of scientists comparing the full genomes of the two species concluded that most Europeans and Asians have between 1 to 4 percent Neanderthal DNA. Indigenous sub-Saharan Africans have no Neanderthal DNA because their ancestors did not migrate through Eurasia.

Thomas Jefferson was descended from the Middle East : Strange as this sounds, this can actual be proved from the genetic mutation his gene shows. You can read more about it here - http://www.sciencedaily.com/releases/2007/03/070328111115.htm

One of the few telescopes left in the Southern hemisphere. We need them! h/t +Charles Strebor and +Ted Ewen.

Save the Mopra Telescope & Map the Milky Way

We have spent the last four years mapping the Southern portion of our Milky Way Galaxy with the Mopra Radio Telescope in Australia. However, due to drastic budget cuts the telescope will be shut down at the end of September, leaving our map unfinished and our knowledge incomplete. Help us finish the survey and make it public, so that we can put the Milky Way on the map.

+Jonah Miller explains general relativity....

General Relativity is the Dynamics of Distance

This is part two in a many-part series on general relativity. Last time, I described how Galileo almost discovered general relativity. In particular, I told you that gravity isn’t a force. In fact, gravity is the same as acceleration. Now, this is a completely crazy idea. After all, we’re all sitting in the gravitational field of the Earth right now, but we don’t feel like we’re moving, let alone accelerating. But let’s take this crazy idea at face value and see where it leads us.

(To read this post in blog form, go here: http://www.thephysicsmill.com/2015/08/03/general-relativity-is-the-dynamics-of-distance/)

(If you haven’t read my previous post on why gravity is acceleration, I recommend you do so now. It is here: http://www.thephysicsmill.com/2015/07/26/galileo-almost-discovered-general-relativity/)

But first, we need to make a brief detour  and discuss the Doppler effect.

The Doppler Effect

The Doppler effect is a bit complicated (especially for light), so I won’t go into too much depth. Instead, I’ll describe it by analogy. (I’ve given the same analogy before, in my article on the expanding universe. So if you remember, you can skip all this. See: http://www.thephysicsmill.com/2013/03/24/receding-horizons-dark-energy-and-the-expanding-universe/)

Imagine that Paul Dirac [1] and Leopold Kronecker [2] are playing catch, as in figure 2. Each second, Kronecker throws a ball to Dirac, who catches it. Thus, the frequency of balls that Dirac catches is 1 Hertz (Hz)—one per second, or one inverse second.

But now imagine that Dirac starts backing away from Kronecker, as shown in figure 3. Kronecker continues to throw at a rate of one ball per second. However, since Dirac is moving away from the balls, each one takes longer to get to him. Thus, he catches the balls at a rate slower than one per second…say, one every 1.5 seconds.

A similar thing happens with both light and sound. (In the case of sound, we call it the acoustic Doppler effect [3].) Light is a wave. It has peaks and troughs which wiggle up and down in time, as shown in figure 4. The number of peaks (or troughs) per meter is called the wave number.  The speed at which it wiggles up and down in time is called the frequency. The two are related by the speed of the light wave, which is always constant (see: http://www.thephysicsmill.com/2012/11/19/the-speed-of-light-is-constan/), so they’re basically interchange-able.

The frequency of a light wave is analogous to the frequency at which Kronecker throws balls at Dirac. Instead of counting the number of times Dirac throws the ball, we count the peaks of the wave. The frequency of a light wave also determines its color; high frequencies are blue, while low frequencies are red.

This means that if Kronecker fires a green laser at Dirac, and Dirac moves away from him, the laser light will appear more reddish to Dirac than it does to Kronecker. This is called a redshift. If Dirac were moving away from from Kronecker at an increasing rate, in other words if Dirac were accelerating, the redshift would be even more pronounced.

Gravitational Redshift

So what does all this have to do with gravity? Well remember, gravity is acceleration. So we should be able to see a Doppler-like effect just by moving from a region with strong gravity into a region with weak gravity, or vice-versa. To see what I mean, imagine that Kronecker and Dirac are up to their old tricks. But this time, imagine that Kronecker is on Earth, and Dirac is in space, as shown in figure 5.

Kronecker fires a green laser up at Dirac. Now, remember: gravity is acceleration. Both Kronecker and Dirac are in a gravitational field, so they’re both accelerating. But Kronecker is in a stronger field, so he’s accelerating more. This means that, from Dirac’s perspective, Kronecker is accelerating away from him. Therefore, by the time the light reaches Dirac, he sees it redshifted because of the Doppler effect.

In the context of general relativity, we call this gravitational redshift, and it’s a real effect. We need to take it into account when we read signals sent to us from gps satellites, for example [4].

Redshift, Distance, Time

The peaks and troughs of light make it an extraordinarily good ruler. If you know the wave number of a wave of light, you can count the number of peaks and in the wave between two places and calculate how far away those two places are from each other. In a very real sense, distance is defined by this procedure [5].

How, then, do we interpret the redshifted light that Dirac sees? If light on Earth is redshifted when it goes into space, that light stretches out. The distance between adjacent peaks in the light wave grows. Does this mean that distance itself grows?

Yes. It means exactly that.

In a strong gravitational field, distances are shorter than in a weak gravitational field. Indeed, because the wave number of a wave and the frequency of a wave are interchange-able, this also means that times are longer in duration a strong gravitational field than in a weak gravitational field.

We started with the crazy (but true!) idea that gravity is the same as acceleration. But this has lead us to an even crazier (but still true!) idea: gravity shrinks distance and stretches duration.

This is what people mean when they say that gravity is a warping of space and time (or suggestively, spacetime). The very way that we measure distance is distorted by a gravitational field.

And general relativity is the dynamics of distance.

Next time we’ll talk about how a warped spacetime creates the illusion of a gravitational force.

Further Reading

I took the gravitational redshift argument directly out of the excellent textbook Spacetime and Geometry by +Sean Carroll. If you have a good background in math and you want to learn general relativity, I highly recommend it.  You should also check out his amazing blog: http://preposterousuniverse.com/

Here are some other resources:

1. This is a nice video on the Doppler effect: https://youtu.be/h4OnBYrbCjY

2. The PBS Spacetime Vlog has an excellent series of videos on general relativity. The first two videos cover what I’ve covered so far, but from a different perspective. You can find them here:

On April 6, marine scientist Tim Essington of the University of Washington, published a study in PNAS that found intense fishing does amplify forage fish collapses. He looked at patterns of 55 forage fish populations around the world over multiple decades and saw that collapses were much deeper and more frequent when fishing occurred.

You can find Essington's study on the PNAS website here: http://m.pnas.org/content/early/2015/04/01/1422020112.abstract

If you liked yesterday's Jupiter image....

Then wow... have I got something for you....

So if you're wondering what I'm talking about, yesterday I shared out an animation from multiple shots taken by the +Hubble Space Telescope of #Jupiter  and its three moons: #Europa   #Calisto  and #Io . (http://goo.gl/IRI4p7)

But as was revealed in yesterday's #HubbleHangout , the team was also able to resolve the tiny moons Amalthea & Thebe!! Below is a #gif  of multiple frames taken by Hubble.

To give you a bit of perspective, the average radius of Amalthea is about 85 kilometers while the average radius of Thebe is about 49 kilometers. I say average (or mean) radius, because they're so tiny... they're not really spherical... but that's realllllly tiny to be able to resolve not only the object, but their shadow!

+The TerraMar Project explains how tides may have clues to climate change....

Canadian and American scientists are teaming up with Australian researchers to study some of the largest waves on the planet in the Tasman Sea. Oh, and did we mention those waves are beneath the ocean's surface?

Also known as internal tides, these underwater waves are the result of water getting pushed against features on the seafloor such as ridges and mounts. The turbulence caused by these obstructions can create underwater waves hundreds of meters high that can be imperceptible at the surface but powerful enough to move whales and submarines. Scientists speculate internal tides can provide insights to climate change and fisheries. The Schmidt Ocean Institute has a great explanation on their website, and the R/V FALKOR will be involved in the expedition: http://www.schmidtocean.org/story/show/2963

According to Dr. Pete Sutton, University of Tasmania's Institute for Marine and Antarctic Studies (IMAS) and part of the research team, "The goal of this research expedition is to discover and measure the procession of those internal tidal waves and to document the various phenomena that occur when they impact the deep continental slopes. The internal tides and turbulent mixing that occurs in the deep sea off Tasmania is thought to affect the overall circulation of the global ocean. Understanding these processes is a critical step in predicting our climate." You can find more of his comments on the University of Tasmania's website: http://www.imas.utas.edu.au/right-column-content/whats-new3/news-imas/tracking-the-deep-ocean-tides-of-the-tasman-sea2

Pink was for boys and blue was for girls : At least before the modern obsession of going the other way. It kind of proves that the color palette we expect for boys and girls is based on societal pressures. At least now we know better!

Roosevelt : Little Franklin Delano Roosevelt sits primly on a stool, his white skirt spread smoothly over his lap, his hands clasping a hat trimmed with a marabou feather. Shoulder-length hair and patent leather party shoes complete the ensemble. Social convention of 1884, when FDR was photographed at 30 months, dictated that boys wore dresses until age 6 or 7, also the time of their first haircut. Franklin’s outfit was considered gender-neutral.

How conventions came to be : Why have young children’s clothing styles changed so dramatically? How did we end up with two “teams”—boys in blue and girls in pink? "It’s really a story of what happened to neutral clothing,” says Paoletti, who has explored the meaning of children’s clothing for 30 years. For centuries, she says, children wore dainty white dresses up to age 6. “What was once a matter of practicality—you dress your baby in white dresses and diapers; white cotton can be bleached—became a matter of ‘Oh my God, if I dress my baby in the wrong thing, they’ll grow up perverted,’ ” Paoletti says.

Pink for boys - since it is a stronger color : a June 1918 article from the trade publication Earnshaw's Infants' Department said, “The generally accepted rule is pink for the boys, and blue for the girls. The reason is that pink, being a more decided and stronger color, is more suitable for the boy, while blue, which is more delicate and dainty, is prettier for the girl.”

It all changed in 1985 : Prenatal testing was a big reason for the change. Expectant parents learned the sex of their unborn baby and then went shopping for “girl” or “boy” merchandise. (“The more you individualize clothing, the more you can sell,” Paoletti says.) The pink fad spread from sleepers and crib sheets to big-ticket items such as strollers, car seats and riding toys. Affluent parents could conceivably decorate for baby No. 1, a girl, and start all over when the next child was a boy.

Gendered roles : “One of the ways women thought that girls were kind of lured into subservient roles as women is through clothing,” says Paoletti. “ ‘If we dress our girls more like boys and less like frilly little girls . . . they are going to have more options and feel freer to be active.’ ”

What Exactly Are Gold, Frankincense, and Myrrh?

This is not about any religion or a discussion of religion.  I just wanted to find out what was so important about Gold, Frankincense and Myrrh that they were considered valuable.  I ask that any comments please be strictly materials science related.

Gold is a chemical element with the symbol Au and atomic number 79. It is a dense, soft, malleable, and ductile metal with an attractive, bright yellow color and luster that is maintained without tarnishing in air or water.

What Exactly Are Gold, Frankincense, and Myrrh?

This is not about any religion or a discussion of religion.  I just wanted to find out what was so important about Gold, Frankincense and Myrrh that they were considered valuable.  I ask that any comments please be strictly materials science related.

Gold
This one is easy, it is gold, the shiny metal that has been a symbol of wealth since it was first discovered.  
Gold is a chemical element with the symbol Au and atomic number 79. It is a dense, soft, malleable, and ductile metal with an attractive, bright yellow color and luster that is maintained without tarnishing in air or water. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements, solid under standard conditions. The metal therefore occurs often in free elemental (native) form, as nuggets or grains in rocks, in veins and in alluvial deposits.  ⓐ

This metal has been a valuable and highly sought-after precious metal for coinage, jewelry, and other arts since long before the beginning of recorded history. Gold standards have sometimes been monetary policies, but were widely supplanted by fiat currency starting in the 1930s. The last gold certificate and gold coin currencies were issued in the U.S. in 1932. In Europe, most countries left the gold standard with the start of World War I in 1914 and, with huge war debts, did not return to gold as a medium of exchange. The value of gold is rooted in its medium rarity, easily handling, easy smelting, non-corrosiveness, distinct color and non-reactiveness to other elements; qualities most other metals lack.  ⓐ

Besides its widespread monetary and symbolic functions, gold has many practical uses in dentistry, electronics, and other fields. Its high malleability, ductility, resistance to corrosion and most other chemical reactions, and conductivity of electricity has led to many uses, including electric wiring, colored-glass production, and gold leafing.  ⓐ

Most of the Earth's gold probably lies at its core, the metal's high density having made it sink there in the planet's youth. Virtually all discovered gold is considered to have been deposited later by meteorites that contained the element, with the asteroid that formed Vredefort crater having been implicated in the formation of the largest gold mining region on earth, Witwatersrand basin  ⓐ
  
Gold has been used for more than 75 years to treat rheumatoid arthritis (RA). (Indeed, gold preparations are among the original medications targeting this form of arthritis). Before its use in RA, gold was used to treat infections, including tuberculosis. Gold is one of a class of medications known as disease-modifying antirheumatic drugs (DMARDs), because it not only decreases the pain and swelling of arthritis but also can prevent joint damage and disability. While gold can be very effective at suppressing the signs and symptoms of RA for some patients, it is used less frequently as new, better tolerated medications have been identified.

Gold nanoparticles are also used in cancer treatment. 
As a delivery agent for anti cancer drugs.

And tiny particles of gold are also used in thermal cancer treatment.

Frankincense, also called olibanum  
Derived from tree sap, or gum resin, both frankincense and myrrh are prized for their alluring fragrance. Frankincense is a milky white resin extracted from species of the genus Boswellia, which thrive in arid, cool areas of the Arabian Peninsula, East Africa and India. The finest and most aromatic of this species is Boswellia sacra, a small tree that grows in Somalia, Oman and Yemen. These plants, which grow to a height of 16 feet (5 meters), have papery bark, sparse bunches of paired leaves, and flowers with white petals and a yellow or red center  ⓑ

The English word is derived from Old French "franc encens" (i.e. high quality incense)[1] and is used in incense and perfumes.  There are four main species of Boswellia that produce true frankincense and resin from each of the four is available in various grades. The grades depend on the time of harvesting. The resin is hand-sorted for quality.  

I found two dissertations on Frankincense and they are a fascinating, very detailed discussion of Frankincense and its uses. More than you ever wanted to know about this sweet smelling incense.

Myrrh  
Myrrh is the aromatic resin of a number of small, thorny tree species of the genus Commiphora, which is an essential oil termed an oleoresin. Myrrh resin is a natural gum. It can also be ingested by mixing it with wine.  ⓓ

When a tree wound penetrates through the bark and into the sapwood, the tree bleeds a resin. Myrrh gum, like frankincense, is such a resin. When people harvest myrrh, they wound the trees repeatedly to bleed them of the gum. Myrrh gum is waxy, and coagulates quickly. After the harvest, the gum becomes hard and glossy. The gum is yellowish, and may be either clear or opaque. It darkens deeply as it ages, and white streaks emerge ⓓ

Myrrh's uses are similar to those of frankincense, with which it is often combined in decoctions, liniments and incense ⓓ

Myrrh is a common ingredient of tooth powders. Myrrh and borax in tincture can be used as a mouth-wash. A compound tincture, or horse tincture, using myrrh is used in veterinary practice for healing wounds. Meetiga, the trade-name of Arabian Myrrh, is more brittle and gummy than that of the Somalian variety and does not have the latter's white markings. ⓓ

The oleo gum resin obtained from Commiphora species, myrrh is well known as a fragrance used in incense and in perfumes. It is also used in traditional medicine for treating inflammation, stomach problems, asthma and other bronchial conditions.  Studies indicate that myrhh has anti-inflammatory, cytotoxic, anti-trichomonas  and antipyretic effects in vitro and in mice  ⓔ

Promising : The TWEETHER project will result in a powerful and compact transmission hub, based on a novel travelling wave tube power amplifier and an advanced chipset in a compact terminal, with performance far outweighing any other technology. After three years of design and development, the system will be tested in a real operating environment.

New idea : Professor Paoloni said the answer was the exploitation of unused portions of the spectrum but at higher frequencies. The recent outstanding advancements in the field of vacuum electron devices and solid state electronics using millimetre wave frequencies opens the route for the breakthrough in wireless high speed data communications.

Why do plants matter : Some of the reasons are obvious. Others not so much. Plants provide food, they help fix Carbon, through photosynthesis, and they create oxygen. But there is so much more they do, which is fascinating.

Plants are medicine factories : Right from the creation of complex sugars, plants also make Vitamin C, painkillers, psychotropics and even now, plants are found to synthesize new chemicals which we use in medicine.

Plants communicate : In more ways than one.... using chemical, electrical and airborne signalling, plants are able to produce defensive weapons and warning signals which can alert their neighbours.

Why Nanomaterials are fascinating (Or how a dog becomes a cat, becomes a hummingbird) : Well, any material can be a Nanomaterial. A Nanomaterial is purely something reduced to a size of 1 to 100 nms. So why the fuss? For one, unlike macro materials, Nanomaterials can be two dimensional. As we get smaller and smaller, they exhibit properties which confound us.  One must remember though, these are not chemically changed. All that is done is the size of the particles is made smaller and smaller.

In Nanotechnology, what is important about materials is NOT really what they are made of, but how small they are. This is different than every other materials age in human history.

In Nanotechnology, what is important about materials is NOT really what they are made of, but how small they are. This is different than every other materials age in human history.

Magnetism example : Atoms can have magnetic moments... Why is this? Due to the spin of unpaired electrons. A magnetic moment aligns with an external field. Let's take the example of CoCr (Cobalt Chrome Alloy). At the macro size, it displays no magnetism. This is because when at the macrosize, domains cancel each other out. These are called 'Bulk Ferromagnets' and can be electromagnets. So these sizes do not get highly magnetized and can be called permanent magnets (if enough of the domains align in one direction). Let's say these behave like Dogs..

As you go smaller, from 20nm grain size to 80 nm grain size, The magnetism in this powder will depend on volume. It is harder to magnetize these particles, but when these are magnetized, they resist going back to their original state. These are single domain magnets and once magnetized, they stay that way; though they are easy to magnetize and demagnetize. Let's say these behave like Cats....

When you go down to even smaller size, the ferromagnets are smaller than 20 nm in size, they are very, very small, not much bigger than molecules. They are easier to magnetize and flip. So easy to magnetize and flip, that this is a property used in MRI tests. Superparamagnets have fluctuating magnetic moments with no applied field, but with applied field become magnetized easily. These are called superparamagnets.  Let's say these behave like hummingbirds.

New Biodegradable Suture Anchors

When a person has a bad shoulder injury like a torn tendon, surgery is required.  The surgeon will use anchor screws for sutures that attach to the bone to do the repair.  These anchor screws have to be strong enough to carry the load until the body has a chance to heal.  Up to now surgeons have been using materials that need to be left in place or removed after the healing process is over.  "Researchers at the Fraunhofer Institute for Manufacturing Technology and Advanced Materials in Bremen, Germany have been working on durable implants that degrade and slowly dissolve into the body for further secretion."

No other joint in the human body is as highly mobile as is the shoulder. However, it is also very sensitive and prone to injury, with athletes being particularly affected. The most common complaints include tendon rupture, which have to be treated surgically. The surgeon fastens the cracks using suture anchors. Such implants used to be made of titanium or non-degradable polymers – with the disadvantages that either they remain in the body even after healing has occurred or doctors have to remove them in a second procedure.  ⓐ

The researchers developed anchor screws that are designed to slowly biodegrade while keeping their strength as long as needed. They are made from a metal - ceramic composite and manufactured using a powder metallurgy process. 

These materials are to be gradually absorbed by the body while, at the same time, new bone tissue is formed. Ideally, the degree of degradation is adapted to the bone growth so that the degradation of the implant meshes with the bone formation. For this reason, the scientists are developing materials with specifically adjustable degradation. The challenge: The implants have to be mechanically stable enough during the entire healing process so that they are able to fix the bone in place. At the same time, they cannot have any allergenic effects or cause inflammation. The researchers at IFAM are relying on metal-ceramic composites.  ⓐ

A metal component based on an iron alloy is being combined with beta-tricalcium phosphate (TCP) as the ceramic component. “Iron alloys corrode slowly and ensure high mechanical strength, while ceramic decomposes quickly, stimulates bone growth and aids the ingrowth of the implant”, Imgrund says to explain the advantages of this material combination.  ⓐ  (Dr. Philipp Imgrund, manager of the Medical Technology and Life Sciences business field at IFAM.)

Powder injection molding is used to manufacture the material composite due to its ability to produce complex structures cost-effectively and in large numbers. Properties such as density and porosity can be controlled selectively – an important factor, since high density and low porosity result in high mechanical strengths. The process also allows materials, available as powders, to be mixed in any proportion prior to processing.  ⓑ 

The materials are available as powders and can be mixed in any proportion prior to processing. But what proportion is the right one? In laboratory experiments, the researchers have found the optimum composition of the materials for the suture anchor. The demonstrator consists of 60 percent iron and 40 percent ceramic. “It is important to determine the right amount of ceramics as a function of the powder amount. If the proportion is too high, the material will be brittle. On the other hand, the tricalcium phosphate accelerates the degradation of the implant,” says Imgrund. The researchers have succeeded in doubling the degradation rate from 120 to 240 micrometers per year in the laboratory model. The shoulder anchor would be absorbed by the body within one to two years.  ⓐ

If you think the weather’s acting strange, you’re correct. Extreme weather in the United States is trending upward, and human-caused climate change has already been blamed for much of it – most recently in connection with the California drought.

But along with extreme weather we’re also getting extreme contrasts. What on Earth is going on when New York gets endless rain and San Francisco none, and when one part of the country is freezing while another suffers under record heat?

You guessed it, rising temperatures have something to do with it – and here’s how.

Rain patterns are changing

In the Northeast, the combination of more moisture in the atmosphere from a warmer world and changes in circulation patterns are bringing more rain. In the Southwest, meanwhile, rainfall is suppressed by a northward expansion of high pressure in the subtropics.

If you think the weather’s acting strange, you’re correct. Extreme weather in the United States is trending upward, and human-caused climate change has already been blamed for much of it – most recently in connection with the California drought.

But along with extreme weather we’re also getting extreme contrasts. What on Earth is going on when New York gets endless rain and San Francisco none, and when one part of the country is freezing while another suffers under record heat?

You guessed it, rising temperatures have something to do with it – and here’s how.

Rain patterns are changing

In the Northeast, the combination of more moisture in the atmosphere from a warmer world and changes in circulation patterns are bringing more rain. In the Southwest, meanwhile, rainfall is suppressed by a northward expansion of high pressure in the subtropics.

The crippling drought now plaguing California is due to a persistent high pressure system off of the coast that is deflecting storms away from the region. A recent study shows that these systems are much more likely to occur with human-caused climate change.

Rain is more intense

Heavy downpours are controlled by cloud mechanisms and moisture content, which are both changing as global temperatures rise. Clouds that can dump a lot of rain are more common in a warmer atmosphere.

More evaporation has led to more moisture in the atmosphere which, in turn, leads to more intense rainfall when it rains. That helps explain why the entire U.S. is experiencing more heavy downpours – even in the drought-stricken West.

Droughts are taking hold

Rain and evaporation will determine how moist the soil will be. So although evaporation is increasing nationwide due to warmer temperatures, higher precipitation in the Northeast yields a net increase in soil moisture in that part of the country.

In the Southwest, on the other hand, the drop in overall precipitation brings drier conditions that spawn or magnify drought. As the soil there dries out, the incoming sunlight will heat the ground instead of evaporating water from the soil. This creates a vicious cycle of more heat and less rain.

Flooding is more common

The potential for flooding, meanwhile, depends a lot on what's going on with the soil. The higher the soil moisture content, the higher the chance that there will be more runoff from rainfall.

Because soil moisture is increasing in the Northeast, flooding events are on the rise. Fortunately for the region, many heavy rain storms occur in the summer and fall when soil moisture is low and the ground can absorb more water.

On the other hand, the sea level has risen by a foot since the 1900s in the Northeast. That, in turn, contributes to more flooding.

Disaster costs are also rising – but there is hope

In 2013, intense storms, severe regional drought, and extreme flooding led to more than $9 billion in disaster costs in the U.S. alone. It’s uncertain what the total bill was if you factor in ongoing agriculture, human health and infrastructure losses from changing weather conditions

Unless we curb emissions of heat-trapping gases, scientists expect these trends to continue and worsen – and the contrast between wet and dry areas of the U.S. will likely become even sharper. Our hope now is that the push for climate action amps up so we can finally set ourselves on a better path for the future.___

The Mecanum wheel
 A design for a wheel which can move a vehicle in any direction. It is sometimes called the Ilon wheel after its Swedish inventor, Bengt Ilon, who came up with the idea in 1973 when he was an engineer with the Swedish company Mecanum AB.
It is a conventional wheel with a series of rollers attached to its circumference. These rollers typically each have an axis of rotation at 45° to the plane of the wheel and at 45° to a line through the centre of the roller parallel to the axis of rotation of the wheel. By alternating wheels with left and right-handed rollers, in such a way that each wheel applies force roughly at right angles to the wheelbase diagonal the wheel is on, the vehicle is stable and can be made to move in any direction and turn by varying the speed and direction of rotation of each wheel.

Moving all four wheels in the same direction causes forward or backward movement, running the wheels on one side in the opposite direction to those on the other side causes rotation of the vehicle, and running the wheels on one diagonal in the opposite direction to those on the other diagonal causes sideways movement. Combinations of these wheel motions allow for vehicle motion in any direction with any vehicle rotation.

Theft

So sci fi August is over for me. While browsing the hashtag for others' works, I came across a community moderator who, instead of resharing two of my images, took poor quality screen shots of my work, cropped them so my old JMD signature I used to use on my images was really visible, and then posted to her community.

My text is there, my name is there, but the image is her screen shot rather than my work. She hasn't responded.

Lame.

This image, btw, it's #SOOC, from my S5.

Have a good day/evening/morning!

Day 21

Adrift

I lay there in space, drifting. The hull is ruptured. My body broken. Awaiting the final blast.

SciFi August Continues!

Last year's SciFi August was great fun, and quite a few of you participated, so it had to happen again. For this month of August I will be exploring outer space, inner space, hyper space and other SciFi spaces and places on my appropriately named Galaxy S5. I would very much like it if you joined in on the fun.

Tag any of your creative work that you created during August with the tag:

#SciFiAugust.

These can be in the forms of imagery, painting, story, poetry, sculpture, you name it. Just keep it constrained to science fiction and to August.

Science Posts : are often about new discoveries or about science and related technology. I post a lot within this area. I have often found that while my posts have engagement, it gets hard to explain why the commenter has to stick to the science.

Why can't I talk about my experience : Of course you can, but one has to preface it by saying it is my experience, or its not something backed by research. And be ready to be called on it. Very often commenters will continue to talk about their experiences as if that 'proves' something. Experiences do not make science. It is an experience. What you observe may not be what another person observes. Or it may not be repeatable. (See the Scientific method here http://en.citizendium.org/wiki/scientific_method )

What you observe may not be what another person observes. Or it may not be repeatable. (See the Scientific method here http://en.citizendium.org/wiki/scientific_method )

How to make your point scientifically : Science posts may be wrong. That is the nature of science. Sometimes the science may be based on hypothesis which may have counterpoints, but these are continuously tested and refined. Theories are based on observations, so they have a body of work behind them. These are not 'guesses.' Be respectful to the original poster, since often science posts have a lot of work and research which has gone into it. Make your point with research from reputable sites and link back to the research. If you are not sure about it's veracity, ask an expert (There are many on Google Plus).

Does a study make it true : This one is fraught with issues. Often studies may not have a large enough sample size. Or the conclusions one may draw from a study may not be correct. Most scientists are extremely wary of making assertions, even in their own field. They know that there are a lot of variables which need to be taken into account. Science begins with skepticism. Every study needs to be evaluated.

Making your point : Oftentimes, you can make your point with just one comment on a post. Sometimes you make need to make a followup comment. Don't keep repeating your point, making the same assertion again and again. Talking over people does not make you right. It only makes them lose respect for what you are trying to say. Calling someone names is the lowest form of engagement. Do not let it sink to that level.

'Converting' someone : Don't comment to 'convert' someone to your point of view. Science is not about who talks louder or says it more often or cites more studies. Its about relevance, facts, study and repetition. (See my earlier post here How to do science : https://plus.google.com/110884604033336753419/posts/VJrxUt6gUmi )

Science doesn't play favorites : Mentioning Einstein does not make you right. Any scientist would tell you that there are things they do not know. The journey in science is the finding out. One has to live with things which are still not known, and scientists are the best at this way of being.

Join in the journey of finding out, rather than knowing : Science is fascinating. It is incredible. It really is. There is so much I learn just by reading and writing (researching) about how things work, its really something everyone should indulge in. It's brain food. Knowing something is the end of asking. Revel in the journey, not the end.

How to Science : Recently, I have been trolled pinged by a number of people who have asked me to talk about perpetual motion machines, thunderbolt universes, how magnetism affects mood, niburu or somesuch and a lot of other such stuff. One chap even 'debunked' the second law of thermodynamics based on a youtube video.... (keep your baloney detection kit ready).

Why science is important : Science is a method. Yes, we make mistakes, make assumptions, make hypothesis, which when supported by observations are elevated to theories.... and here is the main thing, we have to have observations that are repeatable, free of bias and need to be analyzed. This is an iterative process and involves external checks and balances, data recording and rigor. The first such process recorded (from Wikipedia) In the 7th century BCE, Daniel, a Jewish captive of the Babylonian king Nebuchadnezzar,... more »

This is an iterative process and involves external checks and balances, data recording and rigor. The first such process recorded (from Wikipedia) In the 7th century BCE, Daniel, a Jewish captive of the Babylonian king Nebuchadnezzar, conducted a scientific experiment complete with a hypothesis, a control group, a treatment group, and a conclusion.

Is there a way to find verifiable information : Sure, but it still needs to have rigor. A youtube reference is not a good benchmark. Most news sites are also not good indicators. Reputed science sites, reference papers and peer reviewed publications are good places to look. Even then not all of them are the best quality.

Why shouldn't I believe in flying chariots? The Nazca lines prove that chariots can fly : You are free to believe whatever you want. But remember, it is not something anyone will take seriously since your claim is based on belief, not proof or a method which involves rigor, repeatability and removal of bias.

Who should I ask? : Ask people who are experts in their field. There are quality scientists, chemists, biologists, physicists here on G+.... reach out and ask them. There are also sources like askamathematician where you can post your queries. They really do respond.

Calling All Geeks: Can I borrow five bucks? =)
TLDR: http://bit.ly/btckiva .

First off I want to apologize if this comes across as being spammy. I don't generally post things here that are self promotional but in this case I hope you'll all forgive me!

As some of you know, I quit my full time gig over a year ago to start my own business; a worker-owned tech support cooperative based in Somerville, MA called +Boston TechCollective. It's been a hell of a ride and I love not only what I do but my co-owners are some of the best people I've ever worked with!

We've grown considerably in a little over a year and at this point we could really use two people manning the shop and two people doing on-site/remote support. There are only three of us though! As you might imagine, it's stretching us very thin. We've got too much work but note... more »

It's been a hell of a ride and I love not only what I do but my co-owners are some of the best people I've ever worked with!

We've grown considerably in a little over a year and at this point we could really use two people manning the shop and two people doing on-site/remote support. There are only three of us though! As you might imagine, it's stretching us very thin. We've got too much work but not enough revenue to justify hiring a part time person to lighten the load.

That's where Kiva comes in. It's a social lending site that allows people and organizations to get loans of up to $5000. Anyone who wants to support a project will eventually get their money back once the loan is repaid.

For us this relatively small amount of money will mean we can hire a part timer for our shop. That will mean that my co-owner +Yochai Gal will be freed up to do more on-site work (my primary job) which will generate more revenue. In the shop it would mean that +Matt Gabrenya would get some breathing room as well. Eventually we hope to make this part timer a member of our coop which would obviously be good for them as well!

In short it would give us the small boost we need to really get ourselves established!

So What Do You Want From Me?

All I ask is that if you can lend us even five bucks it would be wonderful. I know that times are tough so even if you can't lend, a reshare would be fantastic too!

Here is the link: http://bit.ly/btckiva

Thanks in advance to all of you. From the amazing crew that participates in my #gqotd  to the writers and assorted folks who follow my #gsotd  posts to the friends I've made via Hangouts I feel grateful to you all regardless!___
