Amazing Archimedean screw ! – MechStuff

The name itself gives us an idea that it is invented by Archimedes. Now this man – Archimedes, was an Ancient Greek mathematician, engineer, inventor, physicist, & an astronomer(such a smartass). We are living in 21st century & still we are not able to think stuff like this on our own & this man did it in the 3rd century BC !!!!! We already discussed one of his works – buoyancy & we saw how do ships float ? So the Archimedean screw OR screw pump is just a simple machine consisting a cylinder & a helical surface on the inside part of cylinder. Basically, it...

The theory of parallel universes is not just maths – it is science that can be tested -

The existence of parallel universes may seem like something cooked up by science fiction writers, with little relevance to modern theoretical physics.

Stephen Hawking says he has a way to escape from a black hole - New Scientist

Researchers have long struggled to resolve what happens to information when it falls inside a black hole, but the famous physicist says he has a solution

How Did Scientists Discover the Neutrino When it Has No Charge and No Mass?

It’s the early 1950s, and people pretty much agree that a neutrino exists. No one has found it, and because it’s nearly massless and completley chargeless no one can figure out how to find it. Learn how two scientist finally managed it.

New theory—If we want to detect dark matter we might need a different approach

Physicists suggest a new way to look for dark matter: They believe that dark matter particles annihilate into so-called dark radiation when they collide. If true, then we should be able to detect the signals from this radiation.
The majority of the mass in the universe remains unknown. Despite knowing very little about dark matter, its overall abundance is precisely measured. In other words: Physicists know it is out there, but they have not yet detected it.

A small, modular, efficient fusion plant | MIT News

Advances in magnet technology have enabled researchers at MIT to propose a new design for a practical compact tokamak fusion reactor — and it’s one that might be realized in as little as a decade, they say. The era of practical fusion power, which could offer a nearly inexhaustible energy resource, may be coming near.
Using these new commercially available superconductors, rare-earth barium copper oxide (REBCO) superconducting tapes, to produce high-magnetic field coils “just ripples through the whole design,” says Dennis Whyte, a professor of Nuclear Science and Engineering...

What is a ray of light made of?

Light is what allows us to understand the world we live in. Our language reflects this: after groping in the dark, we see the light and understanding dawns.
Yet light is one of those things that we don't tend to understand. If you were to zoom in on a ray of light, what would you see? Sure, light travels incredibly fast, but what is it that's doing the travelling? Many of us would struggle to explain.

Japanese team fires world's most powerful laser

(—A team of researchers and engineers at Japan's Osaka University is reporting that they have successfully fired what they are claiming is the world's most powerful laser. In their paper published in the journal Plasma Physics and Controlled Fusion in 2012, the team described their laser and how it works.

The team now reports that they fired...

Fly Through The Solar System At The Speed Of Light With This Video

Space is really, really big, and there’s been a couple of great videos out there that show off the relative size of objects. This video puts the scale of the solar system into real perspective by showing how it takes you pass through the solar system at the speed of light.
