Le 28 juin 2009, le physicien Stephen Hawking avait organisé une réception au champagne pour les voyageurs du futur. L’astuce est que les invitations n’ont été envoyées que le lendemain de la fête. Forcément, personne n’est venu.

Peut-on passer à travers deux portes à la fois ? Dans la vie de tous les jours c’est impossible, mais dans le monde de la quantique, c’est possible. C’est la fameuse expérience de la double-fente. Les fentes sont les portes et les électrons sont les électrons. Salukes #science #physique

Est-il possible qu’une tasse de café vous envoie un photon dans l’oeil ? La quantique joue avec des probabilités. Elle vous dit pas que c’est impossible, juste que c’est improbable. Il faut accepter de vivre avec l’incertitude.

La conservation du moment angulaire peut se voir de la manière suivante. On calcule la surface que balaye la masse par unité de temps. Cette quantité doit être constante. C’est fondamentalement la seconde loi de Kepler, dite loi des aires. La physique est pas compliquée.

Quand deux trous noirs se frôlent, ils emportent un peu d’énergie en ondes gravitationnelles. Pour la calculer exactement, il faut une variété de Calabi-Yau à six dimensions. L’idée géniale a été d’importer dans la relativité générale l’arsenal de la théorie quantique des champs.

On va essayer de bien comprendre la flèche du temps avec un exemple microscopique (les physiciens parlent de micro-états). La flèche du temps devient alors une sorte de loi de probabilité géante. C’est plus fort que du roquefort. Salukes ✅​ Vidéo longue sur le YouTube. #science #physique

On this Memorial Day, we honor the brave men and women of the United States military who made the ultimate sacrifice in defense of freedom and democracy.

Memorial Day began as Decoration Day, founded to honor those who died to end slavery. It is an inherently abolitionist, antifascist holiday. Not just to mourn what is lost, but to remind us that human beings deserve freedom, and our neighbors are worth fighting for. www.noiceinthecup.us

I'm pleased the Government is taking action to reduce smoking and vaping - to protect young people and help smokers to give up. I welcomed plans to encourage enforcement, giving councils the power to reinvest fines from shops which break the law to help pay for local enforcement.

Healthcare is a right. Single-payer is how we deliver that promise.

Jared Kushner, the unelected grifter. Trump and his crime ridden family, sons, daughters and son-in-law, were ALL unelected. Both times foreign & national interests hijacked the election to control the United States government. Will they ever face justice?! The American people want justice!!

Pence: "This talk of a weaponization fund, the idea of creating a fund that could compensate people that assaulted police officers and vandalized the Capitol that day is totally unacceptable. My hope is the administration will drop it. Drop the idea entirely."

I'm not sure how many are aware that this is happening. But we should be extremely concerned about this. We should not be integrated with the Israeli military. As a matter of fact, we should've cut Israel off decades ago. But right now, it's imperative to Americas survival.✂️✂️ #SheShed
