I tried ESP... wifi on the arduino mega, I had heaps of network dropouts needing a hard reset, I couldn't workout why. Eventually I tried the raspberry pi, it works like a dream and far more versatile, I will never go back to arduino.

The plane has to take off doesn't it, the jet provides a thrust of air backwards, hence the plane moves forward relative to the air until it reaches a balance or speed at which the thrust backwards matches the air friction whilst in forward flight, it doesn't matter what speed the wheels are...

A question regarding the double slit experiment, if you were to replace the detector with a second double slit placed at the location of the expected central peak of the interference pattern, and the detector goes at the usual position for the second double slit what subsequent pattern if any...

I thought the chicken crossed the road to see their flat mate.

Could be a cumulus cloud forming at the dew point of rising hot air from the ground (thermal up rising cumulus cloud) being kicked off by a region of rotor turbulence overhead which is found under some clear blue sky wave wind flow conditions. Sorry this is hard to write on an iPad On the...

Does that mean my left eyeball can see parts of the universe that my right eye can't see. What happens then when both eyes are open. [emoji3]

It may be worth lifting the legs to auto transfuse blood back to the heart in an arrest situation especially if low blood volume was the cause such as in blood loss, dehydration... There is no evidence that squeezing the legs will help in an arrest situation, we do use calf compression devices...

I assume you know the difference between fresh whole blood and packed red cells. Most blood transfusions for lost blood is by units of packed red cells, these can be thought of as collected blood that's then had all the plasma, white cells and platelets removed so you are left with a bag...

You have nothing to be concerned about. Firstly an artery by definition carries blood from the heart to the tissues and a vein is a vessel that returns blood back the the heart, for this following explanation don't consider blood flow to the lungs. Blood flow from the left heart carries...
