A NEW HIGH- SPEED SYSTEM TECH FOR EXTREME WEATHER EVENTS

 

How are you guys? Today we will talk about the extreme weather events that are increasingly frequent and with them also lightning, potentially harmful elements that a group of researchers want to keep at bay with a new high-speed system tech. The idea is certainly ambitious and is headed by a Swiss physicist called Jean-Pierre Wolf, laser expert with a passion for meteorology who managed to set up a consortium dedicated to his project.

MARIE CURIE AND RADIOACTIVITY

  

Radioactivity is the property that atoms of certain elements have to spontaneously emit ionizing radiation. Radiation can simply be defined as energy, examples of radiation are: light, heat and radio waves. The term ionizing also indicates that this type of radiation is able to destroy the bonds inside the molecules, in fact damaging them.

WHEN PHYSICS HELPED THE US WIN THE WAR: HISTORY OF THE ATOMIC BOMB

 

 

We all know what happened on August 6, 1945: the first atomic bomb was dropped on Hiroshima, destroying an entire city and killing thousands and thousands of people.

What could exist only in fantasy books became true: mankind touched its lowest bottom.

WHY IS GLASS TRANSPARENT?

Hello everyone! With today’s post  I’m going to start  a series with the answers  to many common questions from everyday life which may seem predictable or obvious but are not .

 The first question I’d like to answer is “Why is glass transparent?” Have you ever wondered how something like glass can be so invisible?

INTERSTELLAR: MANKIND'S NEXT STEP WILL BE OUR GREATEST

“Mankind was born on Earth. It was never meant to die here.”

The movie

Interstellar is a 2014 American science fiction film written and direct by Christopher Nolan. It stars Matthew McConaughey as Joseph Cooper, Anne Hathaway as Amelia Brand, Jessica Chastain as Murphy Cooper, Bill Irwin as TARS (voice and puppetry) and CASE (puppetry), Ellen Burstyn as old Murphy and Michael Caine as Professor Brand.

Interstellar has some of the most beautiful images of  the space. The space is vast and the depiction of a wormhole accomplishes amazement especially to science fiction space. The black hole is even more amazing and it is a recurrent image throughout the movie. It’s in these lingering shots of a tiny spacecraft floating through the galaxy that we can recognize the influence of Kubrick’s space Odyssey. 

Interstellar include complex but fascinating theories referring to Physics,  thanks to a scientific consultant,  Kip Thorne, who also wrote a book where he explains all the Physics in the film (The Science of Interstellar).

IS IT POSSIBLE TO LIVE NEAR A BLACK HOLE?

If you have seen the renowned film "Interstellar", you probably remember the  protagonists leaving the earth in search for an inhabitable planet near a super massive black hole, but you must know there’s a major mistake in all that.  

 A  research directed by NASA astrophysicist, Jeremy Schnittman,  explains it. In his work Schinttman analyses the probability to find an inhabitable planet at  the right distance from the black hole, in the livable area , heated by the accretion disk . Would you like to know what the mistake in the movie is? You can’t live near a black hole because of the light. What does that mean? The light  I refer to is the light that comes from the surrounding stars . To understand it,  we have to imagine the  gravitational , and in general physical  effects caused by this massive object. First of all the different passing of time. According to Einstein's  relativity , when you are close to an object with a huge mass, the time flows faster . Few hours near the black hole are many years in interstellar space. The second one is the reason why you are reading this article ....  charged particles accelerated by the gravity.

A REVOLUTIONARY DISCOVERY: GRAVITATIONAL WAVES

2017 Nobel Prize for Physics

Rainer Weiss, Barry C. Barish and Kip S. Thorne have won the 2017 Nobel Prize in Physics. The three American scientists are members of the LIGO-Virgo collaboration that discovered gravitational waves in 2015. The price was awarded “for decisive contributions to the LIGO detector and the observation of gravitational waves” , the committee said in a news release.
