Tried hard, but didn't manage to look as mean and crazed as @joerogan did for this photo. https://t.co/Tkk8I2aWsa

After a @joerogan podcast we bonded over our martial arts training. I outweigh him by 70+ lbs, but as an MMA enthusiast he could probably kick my ass. He’s trained to do physical harm. Whereas I, a former NCAA wrestler, am trained to briefly put my opponent’s back on a mat. https://t.co/dniQjS9nHi

One of my dozen brimmed hats. All acquired after living in Texas for six years. Most are outback style. One or two are cowboy-adjacent. Got a fat head. So my hats come from special suppliers — Size 8 (3XL) FYI: Your hat size is your head's circumference in inches, divided by Pi https://t.co/7h13JPrMYh

With new, specialized, ground-based telescopes coming on line, our knowledge of hazardous asteroids and comets will grow exponentially in the coming years. Seems like a bad time to reduce science funding to @NASA . Just sayin'. https://t.co/HRV2QSBBQE

"People shouldn’t be afraid of their governments, governments should be afraid of their people" -V, (Alan Moore, 1989)

As a Columbia alumnus (MA, MPhil, PhD), it’s hard right now to recommend the school to immigrants, with ambitions of academic freedoms and Nobel Prizes — graduates and faculty have won 88 of them — given it cares more about appeasing the Government than about academic integrity. https://t.co/zuLmrtGoup

The President’s wife is a European immigrant. Both parents of the Secretary of State are Caribbean immigrants. Both parents of the FBI Director and the richest person on the World are African immigrants. And 1/3 of the 320 American Nobel Prizes in science have gone to immigrants. https://t.co/qaRIvZRiAo

America is indeed a land of opportunity. Why else would so many immigrants want to come here — all the time — in search of freedom and prosperity. There is no America as we know it without the stories and ambitions of immigrants. https://t.co/vmENuUUYgN

Glad to hear that Harvard, my Alma Mater, stood up to the Federal Government in defense of academic freedoms. It’s a start, but at least their latest declaration aligns with the school’s Latin motto for Truth: “Veritas”. Perhaps other institutions will follow. https://t.co/O0ZkDLTzDO

Elon Musk might be too conservative with his Chainsaw. If he instead fired ALL Federal workers — 100% of Government — (including the President, of course) he would render 3-million Americans unemployed but, looking on the bright side, he would save 4.3% of the Federal budget ! https://t.co/7h6HmmLYe6

Off-loading Federal expenses to the States seems like a sensible idea for a Republican administration, until you realize: Nine of the ten States that rely most on Government funding -- all receiving more money per capita than they pay in taxes -- voted Red in the last election. https://t.co/19NN11GjiP
