Why is the moon slowing down?

Why is the Moon synchronously rotating ?

If the Moon’s spin evolved from faster prograde rates, it could have been captured into a higher spin–orbit resonance than the current 1:1 resonance. At the current value of orbital eccentricity, the probability of capture into the 3:2 resonance is as high as 0.6, but it strongly depends on the temperature and average viscosity of the Moon’s interior. A warmer, less viscous Moon on a higher ecc...

Conundrum Why is the moon white ?

ditions and colour. Eyes and the brain subtract the surrounding bias and help us maintain a constant impression under varying background. How does this relate to the moon? Although the moon may be grey or black, we perceive it as white. The fact that we see the moon as white is actually a visual illusion. Referring to Land’s theory, the eye computes the colour based on relative inputs. The moon...

Is Moore's Law Slowing Down? What's Next?

Slowing down pension indexing: the foreign experience.

Between 1975 and 1983, Canada, Finland, Sweden, the United Kingdom, and the Federal Republic of Germany--countries faced with immediate or long-term financing difficulties in their social security systems--modified their social security pension adjustment procedures. These changes in pension adjustments very often were made in conjunction with other restrictive measures such as increased contri...
