Feynman diagrams depicting the different (decay-)channels for single-top-production mechanisms. The letters refer to top quarks (t), bottom quarks (b), light quarks (q: u, d, s), W bosons (W), and gluons (g). In each case, the incoming particles are shown on the left and the outgoing particles on the right of the diagram. The circles indicate the W-t-b vertex (interaction), whose coupling strength is governed by the CKM matrix element Vtb.

An Experiment on a Bird in the Air Pump1768, Joseph Wright ‘of Derby’A travelling scientist is shown demonstrating the formation of a vacuum by withdrawing air from a flask containing a white cockatoo, though common birds like sparrows would normally have been used. […] The bird will die if the demonstrator continues to deprive it of oxygen, and Wright leaves us in doubt as to whether or not the cockatoo will be reprieved. The painting reveals a wide range of individual reactions, from the frightened children, through the reflective philosopher, the excited interest of the youth on the left, to...

All this talk about under-eye concealer, and about forgoing it lately, has me thinking about the kinds of makeup that people *don’t* wear. Incidentally, I’m actually surprised to hear that so many of you gals (and guys) forgo under-eye concealer! I’m really shocked. I thought I’d be in the minority, but I don’t think I am. Anyway, I’m scrolling through my makeup mental list, and here’s what I’ve got… Powder lipstick. I realize that this is rare, but NARS released a palette of them in the Erdem collection, and even though it was kitschy cool, the lazy lady in me...

If we’re talking about a palette from BECCA, invariably I’m gonna compare it to Chrissy Teigan’s, because it’s the best one BECCA’s ever made. Even after a year, I still go “HOT DAMN, THAT’S GOOD!” every time I bust it out. So the question I faced (haha) today is, “Do the new BECCA BE a Light palettes kick Chrissy’s palette to the curb?” Hey, phones can make you look like a cat now, so stranger things have happened. 😁 The BECCA Be A Light Face Palette ($46, two versions — Light to Medium, and Medium to Dark) With the two...

Music that makes you dumb… A funny analysis made by correlating SAT/ACT score at every college with the favorite music from the corresponding Facebook pages. I feel comfortable with the position of my beloved Bob Dylan, my “dumbitude” is low enough (or my smartitude high enough, whatever). If you liked this, check out the result of the same recipe applied to books: Books that make you dumb —- EDIT I already see, the PC police is on duty right now… Well, of course this is just a joke, something funny, a game, an amusement… It’s not possibly extract scientific conclusions...
