Physicists have figured out how to create matter and antimatter using light

A team of researchers from the Institute of Applied Physics of the Russian Academy of Sciences (IAP RAS) has just announced that they managed to calculate how to create matter and antimatter using lasers. This means that, by focusing high-powered laser pulses, we might soon be able to create matter and antimatter using light. To break this down a bit, light is made of high-energy photons. When high-energy photons go through strong electric fields, they lose enough radiation that they become gamma rays and create electron-positron pairs, thus creating a new state of matter. “A strong electric field can, generally speaking, ‘boil the vacuum,’ which is full of ‘virtual particles,’ such as electron-positron pairs. The field can convert these types of particles from a virtual state, in which the particles aren’t directly observable, to a real one,” says Igor Kostyukov of IAP RAS, who references their calculations on the concept of quantum electrodynamics (QED). NASA Astrophysics A QED cascade is a series of processes that starts with electrons and positrons accelerating within a laser field. It will then be followed by the release of high-energy photons, electrons, and positrons. As high-energy photons decay, it will produce electron-positron pairs. Essentially, a …

The world’s first hydrogen-powered passenger train is coming to Germany The future is here.

The world’s first hydrogen-powered passenger train has been unveiled this week by French transport company Alstom, which will be operating the incredibly quiet and environmentally friendly ‘Coradia iLint’ in Germany from next year. The best thing about the Coradia iLint train is that it only leaks excess steam and condensed water into the atmosphere, which means it offers a zero-emissions alternative to Germany’s 4,000-strong fleet of diesel trains. The train was presented to the public for the first time last week at Berlin’s InnoTrans trade show. Nicknamed the hydrail, it’s set to become the first hydrogen-powered passenger train to regularly operate over long distances. The iLint is expected to run on the Buxtehude-Bremervörde-Bremerhaven-Cuxhaven regional line in the northwestern German state of Lower Saxony, with testing and approval procedures to be carried out later this year, and public access to open up by December 2017. According to German newspaper Die Welt, Lower Saxony’s local transportation authority has so far ordered 14 iLint trains from Alstom, and if they prove to be a success, more will likely be seen in other regional areas of the country. Interest in the train has also been expressed by leaders in the Netherlands, Denmark and Norway. The iLint …

New evidence is forcing scientists to reconsider how the Moon was formed

  New evidence is forcing scientists to reconsider how the Moon was formed Things just got complicated. BEC CREW 13 SEP 2016 For decades, scientists have been debating what it would have looked like when a chunk of Earth broke off and formed our Moon some 4.5 billion years ago. And now new chemical evidence suggests that things were way more violent than we’d assumed, with researchers suggesting that the impact that set our Moon free was “like a sledgehammer hitting a watermelon”. It’s well-established that the Moon was once a part of Earth before it was sloughed off the side and thrown into our orbit, but the circumstances in which this ‘great uncoupling’ occurred has been a topic of heated debate. Until recently, the most widely accepted hypothesis for how the Moon was formed suggested that a Mars-sized object (sometimes called Theia) once collided with the still-developing Earth, about 20 to 100 million years after the Solar System first came together. While our young planet appears to have come out of the collision fairly unscathed, the impact would have caused Theia’s core and most of its mantle to sink into and merge with Earth’s own core and mantle. Of …

Creating a commonwealth: a new approach

Creating commonwealth : a new approach Scene I ( In a room, I am sitting a little perplexed and 2 of my bosom friends,Anurag and Irfan enter the room and ask what happened, why so woebegone?) I: Dear friend, I have been given a great responsibility, and I donot know hoe to go about this. Anurag: Share the problem with us, we will try to resolve this. Irafan: yes, by talking amongst ourselves, we can certainly come up with some ideas that will help you. I: In fact, I have been assigned a project by the UNO to bring an entire habitation out of the extreme poverty. The people in that locality have been living in extreme poverty through many generations. I have been given considerable resources also. But, I am unable to decide the starting point, point from where I should take off. Anurag: see, you cannot solve all the problems in their lives, moreover, something has to be left to be done by them also. Irfan: No, but at least three of their basic problems must be solve. Anurag: which three, please? Irfan: well, they may be toilets and drinking water, nutrition, health centre. Myself: what, they will …

Human Growth round the world

Global height study finds out who grew the most in the past 100 years Get up, stand up. JACINTA BOWLER 27 JUL 2016 933 In a global height analysis based on nearly 1,500 studies, Dutch men and Latvian women topped the charts, standing tallest at heights of 182.5cm and 169.8cm on average respectively. The study found heights have changed dramatically between 1914 and 2014, with South Korean women showing the largest increase of 20.2 cm over the period. Americans are leading the race in another trend – plateauing. The study shows that although humans as a species are still getting taller, countries such as the US, UK, and Japan have stopped or slowed growing significantly in the last 30-40 years. The US, once home to the 3rd tallest men and 4th tallest women in the world, are now sitting in 37th and 42nd place respectively. “This study gives us a picture of the health of nations over the past century, and reveals the average height of some nations may even be shrinking while others continue to grow taller,” said lead researcher Majid Ezzati from Imperial College London in the UK. “Our study also shows the English-speaking world, especially the USA, is …

Reclaiming the common space

Reclaiming the common space I st example (On the cross road, four women are seen standing. One harassed woman is coming with her daughter, daughter’ ankles are bleeding)   The first woman: hey sister, what happened, why your daughters ankle is bleeding? The harassed woman:she was playing on the road, a motorcyclist hit her and sped away. the second woman: but why was she playing on the road? what happened to the wee litttle park by the side of your home. The harassed woman: the wee little park has been turned by some persons in the big car park. The third woman: how come, how is it possible? The harassed woman: I donot know. they say that a common park has now become a common car park. Forth woman: we can have this discussion later, first let us take this girl to some doctor. (All agree.They do to the doctor and they get the girl’s bleeding ankles bandaged. now they are on the road again). First woman: Noew the girl is at ease. Now we have to think as to how to reclaim that common space and convert that bog car park in the wee little park as it once …

A classic formula for pi has been discovered hidden in hydrogen atoms

For the first time, scientists have discovered a classic formula for pi in the world of quantum physics. Pi is the ratio between a circle’s circumference and its diameter, and is incredibly important in pure mathematics, but now scientists have also found it “lurking” in the world of physics, when using quantum mechanics to compare the energy levels of a hydrogen atom. Why is that exciting? Well, it reveals an incredibly special and previously unknown connection between quantum physics and maths. “I find it fascinating that a purely mathematical formula from the 17th century characterises a physical system that was discovered 300 years later,” said one of the lead researchers, Tamar Friedmann, a mathematician at the University of Rochester in the US. Seriously, wow. The discovery was made when Carl Hagen, a particle physicist at the University of Rochester, was teaching a class on quantum mechanics and explaining to his students how to use a quantum mechanical technique known as the ‘variation principle’ to approximate the energy states of a hydrogen atom. While comparing these values to conventional calculations, he noticed an unusual trend in the ratios. He asked Friedmann to help him work out this trend, and they quickly …

four causes, a little skit

Four Cause of Aristotle   A dramatic treatment   ( Four little children are seen dancing on a stage. Two of them are girls and two others are boys. One boy is bigger other the smaller. One girl is bigger, the other is smaller. Suddenly, one girl, the bigger one, comes to the ahead and starts dancing and singing)   Bigger girl: Hey, I am the formal cause of the world, Following me, whole cosmos has unfurled.   Smaller girl: So what, I am the final cause, Unto me all the things pause.   Bigger boy: But without me nothing can be done, I’m the material cause, I’m behind all fun.   Smaller boy: So, what without me you are nothing, I’m efficient cause, I am the king.   ( An old man come from the left side of the stage. There is no light on his face. So it cannot be clearly seen.)   The Old man: hey children, what is all this noise about? How can there be four causes for one thing or one event please explain? Suppose this is a table, then tell me in this case which of you are responsible for which feature of …
