Yeah, I mean I haven't been to the University since March, so this is completely relevant. 👍

Thanks for asking me to waste my time (again)!#tonedeafredtape pic.twitter.com/ZEPJBbN2S9

Ne cherchez pas : oui, c'est la meilleure image de Mars jamais prise depuis la Terre… C'était samedi, au plateau de Calern, avec le télescope de 1 mètre C2PU. On voit magnifiquement les canyons de Valles Marineris. Photo D.Vernet, JP. Prost, C2PU, OCA. pic.twitter.com/wRSOrsyiEL

Proof that “e” is irrational in 1 Tweet

Posted on 2020/10/30 by Carl Robitaille

Proof that "e" is irrational in 1 Tweet:

If e was rational e=p/v= ∑ᵛᵢ₌₀ 1/i! + ∑ᵢ₌ᵥ₊₁ 1/i!
Multiplying by v!

p(v-1)! – ∑ᵛᵢ₌₀ v!/i! = 1/(v+1)+1/(v+1)(v+2)+… <1/(v+1)+1/(v+1)²+…=1/v

The left side is an integer but 0< 1/v <1, hence the assumption is false▪

Incredible traffic jam in Paris as people try to leave the city before 9 pm curfew and before confinement begins at midnight. Traffic is barely moving in every direction as far as the eye can see. Lots of honking and frustrated drivers. pic.twitter.com/6Zn2HCxuPl
