All this time I thought I understood what the most famous equation in physics really meant, and here comes PBS Space Time to give me the real scoop. 

This was a little bit of a mind blow. I need to sit down and think for a while. 

Walter Russell - Periodic Table of the Elementsconsisting of 9 Octaves, showing 2 dimensional representation of a 3 dimensional concept of a 4 dimensional Reality, “The Universal One”, 1927.

In the 1920s, Walter Russell suggested a Periodic Table of Elements - which enhanced and fulfilled the previous Mendeleev Periodic Table of Elements. Walter Russell’s Table consists of Octaves, and, whilst ignored by mainstream science, has proven worthwhile in hindsight, when a “missing” elements had been discovered after several laboratories had isolated the elements which he had foreseen: Deuterium, Tritium, Neptunium and Plutonium, seeing that the Table of Elements of Russell actually already defined them.

A few weeks ago, we reported on the espresso machine NASA and the ESA sent to astronauts aboard ISS. The Capillary Beverage Experiment, known colloquially as the “Space Coffee Cup”, is an accompanying project that aims to use our understanding of fluid behavior in microgravity to design an open cup that simulates earthbound drinking experiences. As you can see above, astronauts are already enjoying drinks with it. The cup’s special shape is optimized so that surface tension can replace the role gravity plays in drinking on Earth. Where we pour drinks on Earth, the cup wicks liquid to the spout using surface-tension-driven capillary action. Right now there are only a handful of 3D printed cups on-orbit and here on Earth, but the company that designed them wants to manufacture glass versions for use here on the ground. So if you’d like your own space coffee cup, be sure to check out their Kickstarter campaign! (Video credit: IRPI LLC; image credit: NASA/IRPI LLC; Kickstarter project link)

They say that if you love it, you should put a ring on it. An international group of scientists love laser physics and made a ring of it, proving their love of existence with the smartest symbol of understanding they could conceive of. The result was an optical Mobius strip, twisting the polarization of laser light into a one-sided surface. Forget cowboys firing guns to make people dance – scientists fired a laser which made light itself spin incredible pirouettes. They directed the beam through a liquid crystal q-plate, and that’s a more Star-Trek-sounding scientific component than a warp drive. This plate split the incoming beam into two parts, which were recombined and focused down to create the optical Mobius strip.

Pew Pew!: 5 Incredible Lasers That Will Change The World

A remote galaxy shining with the light of more than 300 trillion suns has been discovered using data from NASA’s Wide-field Infrared Survey Explorer (WISE). The galaxy is the most luminous galaxy found to date and belongs to a new class of objects recently discovered by WISE – extremely luminous infrared galaxies, or ELIRGs.

“We are looking at a very intense phase of galaxy evolution,” said Chao-Wei Tsai of NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California, lead author of a new report appearing in the May 22 issue of The Astrophysical Journal. “This dazzling light may be from the main growth spurt of the galaxy’s black hole.”

The brilliant galaxy, known as WISE J224607.57-052635.0, may have a behemoth black hole at its belly, gorging itself on gas. Supermassive black holes draw gas and matter into a disk around them, heating the disk to roaring temperatures of millions of degrees and blasting out high-energy, visible, ultraviolet, and X-ray light. The light is blocked by surrounding cocoons of dust. As the dust heats up, it radiates infrared light.

Immense black holes are common at the cores of galaxies, but finding one this big so “far back” in the cosmos is rare. Because light from the galaxy hosting the black hole has traveled 12.5 billion years to reach us, astronomers are seeing the object as it was in the distant past. The black hole was already billions of times the mass of our sun when our universe was only a tenth of its present age of 13.8 billion years.

Saturn’s Spectacular Sights Stun Skywatchers, On Earth, In Orbit And At Saturn Itself

“But if the eyes of our telescopes on Earth were especially keen, the exact moments of opposition — where the Sun is directly opposite to Saturn in the skies — would have brought on a spectacular phenomenon: an intense brightening at one particular point, known as the opposition effect.”

Saturn was just at opposition this past Saturday, appearing bigger, brighter and less shadowed than at any other time of the year. But have you ever heard of the ‘opposition effect’? One of the coolest optical phenomena ever, coming to us courtesy of Cassini!

Quand pendant que je révise mon cours de méthodes d’archéologie je tombe sur une notion de physique plutôt basique (que j’ai vue au lycée) mais que je me rend compte que ne m’en souviens pas tout à fait.

Diffraction Effects

Paul Andersen explains how diffraction can be affected by the size of the wavelength. When waves pass through an opening or move around an obstacle a shadow region is created. The size of the shadow zone will decrease as the wavelength matches the size of the obstacle or opening. This explains why an observer can hear around a corner but not see.

I just realised it’s been about 25 years since watching MacGyver made me study physics, chemistry, and maths at first high school and then Uni…

…and I STILL haven’t had the chance to prevent a nuclear meltdown with nothing but a paperclip and some gum.  I feel kinda disappointed, like science catfished me  ;)

On the bright side, where there’s life there’s still hope?!  ;)
