The physicist and mathematician Freeman Dyson passed away yesterday, February 28. His daughter Mia confirmed the news explaining that her father got injured after falling in his office in Princeton last Wednesday and complications led to his death.

In addition to theoretical studies, Freeman Dyson pursued various technological projects starting with the Orion Project, which aimed to build a nuclear-powered rocket, and subsequently to a class of nuclear reactors called TRIGA (Training, Research, Isotopes, General Atomics) for the production of isotopes for medical use.

Over the years, Freeman Dyson wrote articles that proposed ideas and projects such as the Dyson sphere, a structure built to completely surround a star to use all the energy it emits, and the Dyson tree, a plant created by engineering genetics to grow on a comet useful to create space habitats in which it would generate oxygen. Recently he proposed a variant of this project with the idea of ​​creating plants that absorbed more carbon dioxide.

Twitter has changed its terms of use and now requires an access at least every 6 months. In the event of prolonged inactivity, the accounts will be removed but this will happen gradually in an operation that could take place over several months. The expiration date to be sure not to end up under Twitter’s axe is December 11 and from that day people who make little use of this service but want to keep their account will have to remember at least to access it. The first protests came in particular regarding profiles of dead people and a new tweet from the support service reported that the elimination will not begin before they have found a solution.

Video games had an amazing evolution since their humble beginning and today you can enjoy them on a PC or buy a video game console with the power that not that long ago was limited to supercomputers at really affordable prices. Today there are many options for gamers and it can be confusing if you’re just having your first look into this world, but you just need to get some basic ideas to make the best choice for you.

ESports are becoming something really big with professional video gaming constantly growing. Professional organizations mean greater competitions with media coverage that can go beyond the tournaments’ live streaming and more money. There are arguments about eSports being real sports but the International Olympic Committee already started looking into their possible recognition. Don’t expect to watch eSports at the next Olympic Games but you can be sure that you’ll hear about them more and more. If you’re into gaming and you’re motivated enough, you might consider them as a possible line of work.

Machine learning used to create new polymers

An article published in the journal “npj Computational Materials” reports the results of the use of a machine learning algorithm in the search for new materials. A team of researchers used an algorithm specialized in molecular design trained to recognize candidates with certain properties. In this way they designed polymers with high thermal conductivity, very useful to use for example in mobile technologies connected to 5G.
