How do antibodies find viruses? It's not like they can tell from afar that there is one and then "swim over", can they?	1768
I just watched a repair video of a color CRT monitor. The part I don't understand is, if they R/G/B dots are right next to each other, how can you freely rotate the deflection yoke without getting a rainbow effect?	1
If a car's drag is due to a high pressure zone in front and a low pressure zone in the back, could one try to move that air in the front, through the car (e.g. a pipe) to the back, and reduce drag that way?	1
How is wind able to carry sounds (e.g. a church bell from the neighboring town you usually never hear)? It would seem wind speeds are negligible in comparison to the speed of sound.	1
Can you "breed" mules? After all they are infertile offspring from a horse and a donkey, so you can't directly rely on choosing a desirable mule for procreation.	1
It seems modern physics is increasingly viewing information as the most basic "currency", e.g. when considering black holes' destruction of information. Is there a framework for this way of approaching physics?	1
How does medical triage work? E.g. when there is a natural disaster and far more people arrive in an ER than can be handled, are there established guidelines who to treat and who not? How do you weigh two semi-sick people vs one really sick person (who might not survive no matter what you do)?	1
There are a large number of websites that try to model the future behavior of the pandemic. To my knowledge very few of them assess their own accuracy; are their meta-analysis papers that look at which approaches have done well and which haven't?	1
Relative humidity is heavily dependent on the temperature of the air; what actually happens on the molecular level that enables warmer air to hold more moisture?	1
Sometimes in the summer, especially when the sun is breaking through the clouds, it feels like the sun is "hammering down" much more than on other equally hot but clear-skied days. Is there an objective aspect to this, or is it purely subjective?	1
