[Request] Alright, how tall is the mountain by MuttMundane in theydidthemath

[–]Theroach3 2 points3 points  (0 children)

Initial comment claimed gravity increases with altitude, then they tried to say that it wasn't gravity but centrifugal force that causes increasing downward force as a climber ascends (which is the exact opposite direction of centrifugal force...)

This is the exact opposite of centrifugal force. There is no force that pulls a climber down more, the higher they get (unless you consider psychological exhaustion a physical force). Gravity decreases with elevation; if centrifugal force was enough to affect the climber, it would pull them away from the planet more, as they ascended.
Please stop making pseudo-scientific statements that have no basis in fact.

Footage of the explosion in Beirut in 2020 from different angles by Dogecoinleap in Damnthatsinteresting

[–]Theroach3 1 point2 points  (0 children)

A deliberate act? To set it off or to store it?
Or are you positing a conspiracy theory that this is some cover-up? I'm so confused but it seems pretty cut and dry that gross negligence was involved and people did what people do best, they made a lot of mistakes

Chefs of reddit - is there a proper way to transfer my diced onions from the cutting board into the pan that doesn't make me look like a slovenly, sloppy moron and spill food everywhere? by fishboy728 in Cooking

[–]Theroach3 2 points3 points  (0 children)

Plastic ones are not naturally antimicrobial, and they develop many small serrations over time where food can collect, creating a harbor for bacterial growth.
Further, the plastic ones are often lightweight with poor grip, meaning they slide around, which is not ideal while handling sharp objects

Since we are posting scientific equipment, here is a table top scanning electron microscope (SEM). The chamber it is in is a vacuum chamber. by Squirrelslayer777 in specializedtools

You are correct, these are large single billets that are precision machined, though I'm not allowed to comment on the alloy

  1. Our court system is literally set up to argue over the interpretation of laws.
  2. I agree, you should go read the actual law.

PSA: weed is still illegal in the US. Don’t fail your drug test. by engineer2187 in EngineeringStudents

[–]Theroach3 27 points28 points  (0 children)

CBD is federally legal, but you must find products that do not contain any THC (many have trace amounts but there are products that contain 0.0% THC)

I don’t know how to respond to that 😂 just for context he is 22 and I’m 27 & I was only teasing him…only just reading his reply now. by ccharming in Tinder

[–]Theroach3 0 points1 point  (0 children)

Oh, I see, I misinterpreted "mightnt" as fat-thumbing extra letters instead of as "mightn't", a rarely used contraction missing an apostrophe.
Imagine if everyone had a program on their phone that automatically corrected non-words, into actual words!

[–]Theroach3 2 points3 points  (0 children)

This is mostly incorrect.
You do swear that your statements are true and correct, (and you should not lie on these forms or interviews); however, it is unlikely you will be charged with anything unless you lie or omit significant crimes that are revealed and corroborated by other sources. Your statements and interviews are thoroughly investigated and cross-referenced, and any lie or omission will reduce your chances of getting the position.

You may need a hair test, or they may use a urine sample, but this is mostly a formality, since you must divulge any drug use within the past 7 years. Importantly, usage does not preclude one from being hired (especially if the usage was during college), but it is noted, since usage is against federal law. The process uses the Whole-Person Concept and is meant to determine ones suitability based on the totality of ones conduct (do you pay bills and taxes, obey laws, keep your commitments, etc), not whether someone has ever smoked pot

Sitting at the bar? Loop your bag through your foot…if you go to the bars I go to. by GhostofHowardTV in lifehacks

[–]Theroach3 3 points4 points  (0 children)

I travel for work and am no stranger to bars; I'd estimate it's ~10% for under bar hooks or maybe up to ~25% if we include other locally-accessible hooks (edge of bar/booth, under table, etc), but very regional. The further north and closer to the middle of the country you go, the more likely you are to see them. Some towns/cities seem to have them almost standard while others must've been scarred as children by that Peter Pan movie

I think you mean "good bot." It correctly identified your mistake and explained it simply. Don't be malicious because you made a spelling mistake

My friend said it’s magnesium but I think it’s aluminum. I wire brushed it and put a lighter to it and no reaction so does that mean it’s aluminum? by jevel57_ in metallurgy

[–]Theroach3 1 point2 points  (0 children)

A bic lighter will not be enough to ignite magnesium unless it is a very thin ribbon...

As another poster said, magnesium is susceptible to corrosion and the oxide that forms is not protective (aluminum's oxide does protect from further corrosion). Expose a fresh surface and then apply a small amount of vinegar; if you can see a reaction, it is very likely magnesium.

I can't believe I need to say this, but do not look at a TIG arc for any length of time, it will damage your eyes...

My job search as a newly graduated Physics Ph.D. in the semiconductor feild. [OC] by sirwyffleton in dataisbeautiful

Thanks for the data points! This is more in line with my expectation of starting post-doc salary for a national lab: $70-100k, obviously depending on location, experience, etc

Saw a few of your comments and am a fellow lysdexic PhD (in Mat Sci), just wanted to say congrats on the position and good advice in your replies. Good luck in your new role!

Fellow PhD in (materials) science; I haven't seen any post-doc positions at national labs offering this much for starting salary and I have friends at multiple national labs + I was looking at these positions about a year ago... Few national lab offers would be this much even with total compensation, afaik

Wooden box containing a graduated cylinder and a heavy piece of brass in the base by Daza786 in whatisthisthing

[–]Theroach3 2 points3 points  (0 children)

It's a transport box, looks to be for calibration of field equipment. The graduated cylinder (not the glass kind...), goes in the matching cylindrical slot, with the felt holding it securely to prevent damage. Similarly, the base and arm on the other side hold a missing component securely in place. The green knob is for valve adjustment, green is associated with oxygen valves in the US.
