1.Al Seckel's Richard Feynman

Richard Feynman 11.05.1918 - 04.12.1987

1965 Nobel Laureate in Physics

for fundamental work in quantum electrodynamics, with deep-ploughing consequences for the physics of elementary particles.

Several conversations that Feynman and I had involved the remarkable abilities of other physicists. In one of these conversations, I remarked to Feynman that I was impressed by Steven Hawking's ability to do path integration in his head.
"Ahh, that's not so great," Feynman replied. "It's much more interesting to come up with the technique like I did, rather than to be able to do the mechanics in your head."
Feynman wasn't being immodest, he was quite right. The true secret to genius is in creativity, not in technical mechanics.

2. Reflected light from the surface of the lake ( amusing natural appearances )

While we are in the riding in airplane to wards a small lake in the distance, in the moment we reach the angle of the optimal reflect of the sun’s light from the surface of the small lake, we notice that there are bright and dark tapes in the light that is reflected from the surface of the small lake.Why is that?

Answer: In the distance the lake looks like small hole where the diffraction of the light comes from, so because of that the observer in the plane while flying goes through the minimum and maximim of the diffraction picture.

Heisenberg uncertainty principle;( principle of indeterminism)

The principle that it is not possible to know with unlimited accuracy both the position and momentum of a particle. This principle, discovered in 1927 by Werner Heisenberg ( 1901-76), is usually stated in the form :
∆x∆p_x³h/4ח where ∆x is the uncertainty in the x – coordinate of the participle, ∆p_x is the uncertainty in the x – component of the participle’s momentum, and h is the Planck constant. An explanation of the uncertainty is that in order to locate a participle exactly, an observer must be able to bounce of it a photon of radiation; this act of location itself alters the position of the particle in an unpredictable way. To locate the position accurately, photons of short, wavelength would have to be used. These would have associated large momentum and cause a large effect on the position. On the other hand, using long – wavelength photons would have less effect on the particle’s position, but would be less accurate because of the longer wave-length. The principle has had a profound effect on scientific thought as it appears to upset the classical relation-ship between cause and effect at the atomic level.

The chroniclers concluded that W. Heiserberg must’ve been thinking of his love life when he discovered
the principle of indeterminate
- When there was time, there wasn’t energy;
- When the moment was right, he couldn’t select the location…

Why we can only see one side of the Moon? ( amusing natural appearances )

Why we can only see one side of the moon? Is it because the moon spins so quickly around his circle, so that we can see only one face of the moon? But is this only a coincident?

Answer: The disposition of mass from the moon isn’t spherical symmetrical. Because of that the gravity of the earth creates a moment of force that reflects on the moon. And it brings her to synchronic rotation around her circle. That is called a forced synchronically rotation because the moon always shows her one side.
