Le boson de Higgs expliqué à ma fille

Le boson de Higgs expliqué à ma fille | Sciences & Technology | Scoop.it
Ça sent le roussi pour le boson de Higgs. Je me suis donc dit qu’il était temps que je me lance un défi : essayer d'expliquer en termes simples de quoi il s'agit. Découvrir le boson de Higgs...

 

Un excellent article qui m'a permis de mieux comprendre de quoi il s'agit.

Je vous le recommande.

MIT computer experts unveil RFID chip technology that is 'impossible to hack'

MIT computer experts unveil RFID chip technology that is 'impossible to hack' | Sciences & Technology | Scoop.it

Cutting-edge research from Massachusetts Institute of Technology makes bold claims about RFID technology.

 

"A team of computer experts from the Massachusetts Institute of Technology (MIT) has reportedly constructed a tech-savvy type of Radio Frequency Identification (RFID) chip that is impossible to hack. Alongside researchers from Texas Instruments, the group has already built and tested a number of prototypes that back up their assertions.

RFID chips are now commonplace, used in everything from passports and transport swipe cards to amusement-park tickets. However, as security and privacy concerns among the public have grown in recent years, and with people becoming increasingly suspicious of the technology, the MIT research could be welcome news to those that rely on such chips. (...)"

Cutting-edge research from Massachusetts Institute of Technology makes bold claims about RFID technology.


Now, the researchers claim their cutting-edge findings would mean that security concerns regarding RFID systems become a thing of the past. According to Chiraag Juvekar, an electrical engineering graduate at MIT and a co-author of the research, the new chip has been designed to curb so-called 'side-channel attacks' that can be used to steal the encryption keys contained in RFID technology.

Argentum is like a 3D printer for PCBs | Electronis | Printed Circuit Boards | MakerED | Sciences & Technology | Scoop.it

Cartesian Co.’s rapid prototyping machine is putting the “print" back in printed circuit boards. Despite how far 3D printing has come over the past couple of years, a number of startups have been looking for new ways to take it one step further. Rather than just spit out odds and ends in plastic, what if you could quickly extrude something a bit smarter, like circuit boards, on demand? That’s the idea behind Cartesian Co.’s rapid prototyping machine dubbed Argentum.
