Interesting info-graphics providing a little perspective to the number of people killed by animals. Based on these numbers, the infamous sharks are actually the kindest animals!

I must say that it is a little ironic since technically speaking Humans are the deadliest animal on Earth in terms of number of animals killed by an animal.

Amazing and seemingly gravity defying Floating Castle in the Ukraine.

Strange forces at work, or strong fixings?

The Brachistochrone
This animation is about one of the most significant problems in the history of mathematics: The Brachistochrone Challenge:

If a ball is to roll down a ramp which connects two points, what must be the shape of the ramp’s curve be, such that the descent time is a minimum?

Intuition says that it should be a straight line. That would minimize the distance, but the minimum time happens when the ramp curve is the one shown: a cycloid.

Johann Bernoulli posed the problem to the mathematicians of Europe in 1696, and ultimately, several found the solution. However, a new branch of mathematics, Calculus of Variations, had to be invented to deal with such problems. Today, calculus of variations is vital in Quantum Mechanics and other fields.

Race is a social concept, not a scientific one. - Dr. Craig Venter, one of the first to see biological proof of this by sequencing the human genome. :)  

The New York Times article ► http://www.nytimes.com/2000/08/22/science/do-races-differ-not-really-genes-show.html made it clear even in 2000, after we sequenced the human genome, that race is a social construct, unsupported by scientific data.  

Since 2000, many studies show within the same ethnicity/race there is often far more variation in DNA between  random people than between people of 2 nationalities.  Nationality is a very political social non-scientific label that has no basis in reality, since the nose, eye shape and skin-hair-eye color, appearance are just 0.01% of the DNA.   Science knows of tens of thousands of human genes so far and 3 genes have a role in how much melanin we have in eyes, hair, and skin. A little melanin means white skin, blue eyes, blonde hair; more melanin means darker eyes, hair, skin. :)  It's not worth having wars over such super-tiny differences.  Another article from Washington University highlights the illusion of races being real too ► http://wupa.wustl.edu/record_archive/1998/10-15-98/articles/races.html.  

The future is so raceless :) and peaceful as telepathy, teleportation, shapeshifting will be real and make appearance and nations irrelevant.

TELEPATHY - THIS WILL TRULY END THE IDEA OF NATIONALISM AND FIGHTS OVER LANGUAGE

NANOYOU PART 5 - The Nano Future is a 2 min video about a nanoconcept of human-human telepathy using physical technology, tiny robots that swim in our blood or brain.  Using the same idea, in the future, holographic computers, made of light and/or energy, could assist our brains to use telepathy and navigate other dimensions.  The video talks about the disposable nanobots [the cellphones of the future] enabling us to become Immortal global telepaths. Computers become smaller, so smartphones will become nanobots. Forget email, texting and phone... telepathy is the future :) see, hear, smell, feel, think what others (who answer your '♥telepathy call♥') ☻☺think-feel-hear-see-smell☺☻, full communication :) Brainwaves can be recognized (every time we speak or think a word, there is a voice or brain pattern), as voice can be today, so telepathy will be natural. We'll even move beyond basic sensory + verbal telepathy to conceptual complex trans-linguistic telepathy allowing us to have a communication ☻a billion times richer and more exact than human languages today☻.

In the coming telepathy age we will communicate thru concepts, colors, images & true sensory information instead of language. It'll be a communication a billion times more exact, as you can get a nuanced version of every 'word' or 'bit of info' encoding. ☻Telepathy allows fast transfer of Immortality technologies, volumes of info as vast as the present internet processed in 1 minute by our new brains.  We'll evolve to use a trans-linguistic high speed telepathy & present human languages will disappear. 

Telepathy will obsolete the monetary system even, as blueprints for 'goods' (things are information patterns) are exchanged freely & as pico-technology materializing centers [within human template] provide ability to re-assemble dirt protons-neutrons into any object. We'll also be able to create perfect weather thru a planetary shield.  Compassion & Peace will prevail♥.  

TELEPORTATION - THE END OF NATIONS AND PHYSICAL LOCATION

Teleportation will make fixed physical location outdated and nations will disappear as a result.  Anyone will be able to be anywhere. Professor Zeilinger hopes it will be possible to teleport people in a few decades, as the 7 min video explains: Visions 19 Beam me up :). Certainly ☻♥Immortal Humans♥☻ should be able to teleport, why not. :)  Michio Kaku explains more teleportation in this 1 min video ► Michio Kaku on Teleportation.  Nations and languages will disappear and a multi-planetary Galactic Union of Immortals - GUI :) -  (extended to many planets we will terraform and colonize) will emerge.  

SHAPESHIFTING - CAN BE 10 "RACES" AT ONCE WITHIN SAME DAY

Shapeshifting matter means a tablet will change into an anti-gravity flying belt & we'll overcome the tendency to look at outward appearance - looking instead at Compassionate Intelligence. :) We won't recognize people by their shape, form, gender, height, skin color, which all will be fluid and changeable, but by their kindness & IQ. :)  Here is a shapeshifting gadgets 3 minute video ► Intel Claytronics (Programmable Matter) - DARPA from Intel.  What is more amazing is when we can re-assemble subatomic particles some day, so that we take air, water or anything solid and shapeshift it into any material object or even nutrients in our bloodstream (eliminating the need to eat and fixing all molecular damage, curing all dis-eases, making us ☺☻♥Shimmering Immortals♥☻☺). We will then be able to 'materialize' things out of thin air. :) We will be able to shift our form :), much more than the octopus in this 1 min video: Shapeshifting Octopus, amazing camouflage

Still in the Dark

Dark matter has an interesting history.  It was first proposed to account for the fact that stars in our galaxy move much faster than they should around the galactic core. Evidence of dark matter has been seen in galactic collisions like the Bullet Cluster, as well as through gravitational lensing by galaxies. On the other hand, we have yet to find any direct detection of dark matter particles. In fact, many of the likely candidates for dark matter have been all but eliminated. Then there is the puzzling aspect of dwarf galaxies.

Although dark matter (specifically cold dark matter) works well on large cosmic scales and within large galaxies such as the Milky Way, it doesn’t seem to match up well with dwarf galaxies for several reasons.  One of this is that computer simulations of dark matter predict that spiral galaxies should have much more satellite dwarf galaxies than they actually do.  For example, models predict that the Milky Way should have about 500 satellite galaxies, which in reality it has only 11.  It should also be the case that these satellite galaxies orbit the main galaxy in random directions, but studies of the Andromeda galaxy finds that satellites are somewhat clustered in a plane.  So either something is up with dark matter, or there is an issue with the simulations.

Another problem with dwarf galaxies is known as the cuspy halo (or core-cusp) problem.  Basically if dark matter is “cold”, it should gravitationally clump toward the center of a mass.  This means the distribution of a galaxy’s dark matter halo should have a cusp in the center.  We don’t see such dark matter clumping, even in our own galaxy. This is a particular problem in diffuse dwarf galaxies known as low surface brightness galaxies, or LSBs. With spiral galaxies such a the Milky way, you can argue that the central core of regular matter masks the effects of a dark matter cusp. But since LSBs are diffuse, and they still no cusp of dark matter, that argument isn’t very compelling.

So what if dark matter is wrong?  The main alternative to dark matter are a range of modified gravity models.  These propose that on galactic scales gravity differs from the form described by general relativity.  The most popular of these modified gravity models is known as modified Newtonian dynamics, or MoND.  It turns out that MoND works really well for LSB galaxies.  The stellar motion of LSBs matches the predictions of MoND, so you could call it a win for modified gravity. But modified gravity also has several major problems.  It doesn’t account for effects such as the Bullet Cluster, it is completely contradicted by the clustering of galaxies on large cosmic scales, and it incorrectly predicts the motions of galaxies within clusters.

So where does that leave us? At this point it is generally thought that dark matter not only exists, it accounts for most if not all of the effects we see. We have enough observational evidence to support the existence of dark matter, and effects such as large scale clustering can’t be described by any modified gravity model that also agrees with the experimental limits of special and general relativity.  The big question is whether dark matter can account for all the effects such as LSBs, which it hasn’t done so far. Without a direct observation of dark matter, all sorts of variations have been proposed that might solve the LSB problem among others.

The alternative is that in addition to dark matter there is some new gravitational effect.  Right now most astrophysicists don’t see that as very likely, but if we detect a type of dark matter that can’t account for dwarf galaxies, then it will be clear that modified gravity also plays a role. If that happens, it could revolutionize our understanding of the universe. It would require an extension of Newton and Einstein that are currently the foundation of modern cosmology.

We’re hoping that with more observational and experimental data we’ll be able to solve this mystery.  Until then we’re a still a bit in the dark.
