  Someone more knowledgeable than me will likely join in soon, but depending on your application one op amp might be better than another because of

  • higher slew rate (which affects max frequency)

  • higher unity gain bandwidth (if you need to amplify a wide range on frequencies)

  • better common mode rejection ratio (for working with small signals and electrically noisy environments)

  • lower input bias current (for low- power applications)

  • higher input/ lower output impedance (to not load sensitive instruments/ distort signals)

  And probably loads of other things… cost… thermal…

  Is CS not a good option these days?

  I’m not sure exactly what you’re asking, and I probably don’t know the answer anyway, but I felt compelled to add a safety warning for anyone working with these.

  The CRTs themselves can hold a high voltage for a long time, please be very very careful.

  Absolutely mental that the person who posted this pic didn’t know the reference.

  Bone is classed as a composite material, I think? Or maybe just ceramic…

  13524 (1)

  I think the op medium- level comment is just a typo of this, otherwise wtf is 13542?

  And I’m shocked I’m the first one to say this, surely this is by far the most common way?

• ⁨Comment⁩ on ⁨413524 Gang, rise up!⁩ ⁨⁨5⁩ ⁨weeks⁩ ago⁩:

  I thought it was a typo in the op, but how are you getting from 5 to 4? I always chose a path with just straight lines…

  My hypothesis: the clickbait factoid might be talking about the amount of nicotine that exists in a cigarette butt, which might be different from what a child would practically get in their bloodstream after eating said butt.

  I’m no expert but I’m fairly sure that is basically true in a way. As per zr0’s top-level comment. Forms of life that can make do with less cellular respiration, for example by using external sources to regulate temperature (cold- blooded), don’t need to invite as much oxygen into their cells, and so they get less weird damage over time. Mammals in general have not adopted this strategy.

  Why did you think crocs had holes that size? Haricot are probably the most widely eaten bean in western (croc-wearing) food cultures, so it seems like an obvious design choice.
