Quotes from Jorge Cham

Mass is the property of objects that makes them resist changes in velocity. Simply

A single gram of antiparticles combined with a gram of normal particles would release more than 40 kilotonnes of explosive force, which is more than twice as powerful as the atomic bombs dropped by the United States in WWII. A normal household raisin weighs about a gram, so a raisin plus anti-raisin combination would be a dehydrated weapon of mass fruitation.

this is mathematical speculation by a bunch of overcaffeinated theorists.

biologists have been arguing for decades about the definition of "life" (the zombie-rights activists are a powerful lobby group),

Antiwater would look and feel and behave the same way as regular water except that if you drank it you would explode in a blinding flash of light, which, we admit, would be antirefreshing.

Yes, those ten-billion-dollar twenty-seven-kilometer-long machines are good for more than just finding bosons named after Peter Higgs.

Seeing other cultures is the best way to learn which things you thought were universal but are actually local.

this is more in the category of late-night herb-inspired speculation than actual scientific prediction.

Today, we could maybe store the information contained in one of your toenails if we used every computer in existence.

if there were once more stars visible to us than there are today, what once-obvious facts are we missing because humans arrived nearly fourteen billion years after the party started?

Nap?íklad na urychlení jednoho párátka zhruba na 10 procent rychlosti sv?tla byste pot?ebovali raketu s nádrží v?tší než Jupiter.

Kvarky samy o sob? prakticky nic neváží! Každý z nich váží mí?, než kolik je 1 procento hmotnosti protonu. Ale jakmile dáte dva kvarky dohromady, kdovípro? se jejich hmotnost navýší na stonásobek. To je, jako kdybyste secvakli t?i kosti?ky lega a najednou zjistili, že váží jako t?ista kosti?ek lega.

Today's philosophy questions are tomorrow's precision science experiments.

the entire universe contained in a single point, a singularity, where the mass is enormous, the volume zero, the density infinite, and the parking impossible.

Theorists are a smart bunch (in theory),

if you are on a rocket moving close to the speed of light relative to Earth, then your speed through space is very high. So in order for your total speed through space-time relative to Earth to stay within the speed limit of the universe, your speed through time has to decrease—as measured by clocks on Earth.
