Hey, I am getting interested in the human eye. and I've set up an experiment, to try and prove, how the eye resoultion changes at different lux i.e setting it to 0.1 lux then move 2 slits further away ect. then doing it with dfferent amounts of lux

does anyone have any useful information. or know of a webite that does??


thank you very much!

What a coincidence this subject could come up.

Here is an experiment on eye resolution.

I was watching a documentary yesterday on the Battle of Jutland. One of the key matters was communication between two groups in the British Navy. Admiral David Beatty commanded a group of battlecruisers (lightly armoured battleships) and Admiral John Jellicoe commanded the larger Grand Fleet with battleships. Beatty's group was ahead of Jellicoe's group when a group of German warships were sited. Beatty signaled Jellicoe's group by the old traditional flag/penant method (too early for radio) and took off toward the German ships. Jellicoe (and his watchmen) did not see the Beatty's signal and actually continued away from Beatty.

The point was that Beatty was too far for reliable communication using the flag/penant method.

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...
Hello everyone, Consider the problem in which a car is told to travel at 30 km/h for L kilometers and then at 60 km/h for another L kilometers. Next, you are asked to determine the average speed. My question is: although we know that the average speed in this case is the harmonic mean of the two speeds, is it also possible to state that the average speed over this 2L-kilometer stretch can be obtained as a weighted average of the two speeds? Best regards, DaTario
Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?
