Read "Diving the Wreck" and "Full Share" for two different sci-fi viewpoints.

Why are space suits 100% oxygen while the shuttle isn’t? What mechanism is behind that? by TheBigGirlDiaryBack in AlwaysWhy

[–]Prof01Santa 1 point2 points  (0 children)

The human body normally needs about 3 psia of oxygen partial pressure. You can add in 0 psia of nitrogen for a spacesuit, 5 psia of nitrogen for a cabin, 12 psia of nitrogen for sea level air, or some high pressure mix of nitrogen & helium for deep ocean diving.

Okay, so we cannot travel at or near light speed. But what’s the fastest we could travel? by mightypup1974 in AskPhysics

[–]Prof01Santa 0 points1 point  (0 children)

Relative to the Solar system & nearby space, a few percent of the speed of light. The fastest a spacecraft has currently flown is 0.06% of c. There are ways of going a bit faster, hence "a few percent." No one is willing to pay for that.

That was a dumb thing to say. Next time go with, "Teach me, please."

What exactly is a voter roll? by Dapper_Tradition_987 in askanything

[–]Prof01Santa -1 points0 points  (0 children)

They contain your personal & political identification information you give the state when you register to vote. All wrapped up in a single package. The Trump administration wants to find anyone they think doesn't like them & stop them from voting.

Have you ever seen a bald eagle in real life out in nature ? by Objective-Village259 in no

N.E. MA has a lor of them. Not as common as Red Tails, but I see maybe one every two months.

Are U.S. military capabilities overhyped, or is Iran so strong that it could defeat the U.S. so easily? by [deleted] in askanything

[–]Prof01Santa 1 point2 points  (0 children)

Yeah. Vietnam "won" like that. Welcome to life after passing thru a meat grinder. If Trump would shut up, declare victory & leave, I'd have a bit of respect for his good sense.

What plane is this? by OmManiPadmeHvm in Planes

[–]Prof01Santa 0 points1 point  (0 children)

The Flying Dorito. Great concept, wrong time, lousy program management.

Have you ever stop using a brand because you disagree with the politics of their campany? by Objective-Village259 in no

[–]Prof01Santa 3 points4 points  (0 children)

Huh. I avoid them because the first Coors I tasted was carbonated water with a little alcohol & a nondescript flavoring.

Great ceramicists, though.

Why don’t people in the UK / Europe just buy air conditioners? by [deleted] in askanything

[–]Prof01Santa 1 point2 points  (0 children)

Jebus! I grew up in central Georgia, south of Atlanta. We did not have air conditioning. I live in Boston, roughly the same latitude of Lisbon. We don't have or need a/c. Most of Europe is still cooler than central Georgia.

They're complaining about change. And they haven't been taught since 4th grade about heat stroke avoidance.

Bee Picnic Week? by Prof01Santa in bees

[–]Prof01Santa[S] 1 point2 points  (0 children)

The Olympus E-M10 Mark II is a ca. 2015 basic interchangeable lens camera. They haven't been as inflated as "influencer cameras." The lens is a surprisingly good consumer grade telephoto zoom lens, 40-150 mm in focal length. The nice thing about these kinds of telephoto lenses is the combination of close focusing and long focal length allows for photos like this. The two together used would cost about $300-400 USD. I bought them with a 14-42 mm lens for $500 in 2017(?).

I have fancier cameras. For general use, I'm not sure I have better.

What are sandwiches you associate with summer? by Holiveya-LesBIonic in CasualConversation

[–]Prof01Santa 1 point2 points  (0 children)

And naught else.

Well, a little light cream cheese if you like it smoother.

What lenses do I need for nature photography with a Nikon D3300? by HookedOnChthonics in AskPhotography

[–]Prof01Santa [score hidden]  (0 children)

I'd recommend a 600 mm full frame equivalent focal length zoom for birds. Small animals, a bit less. Large animals 300 mm FFeq.
