Of the total radiation from the sun, only half a billionth reaches the earth.
Convergent evolution of the car speed curve
If the curve for the development of cars’ top speed had converged with the curve for the number of calculations per second in a PC processor over the last 25 years, we would today have cars that could drive approximately 45,000,000,000,000 km/h. That’s the equivalent of driving a trip to the sun in about 15 minutes.
Letters and stars
If you built a bookshelf from the ground to the sun, 1000 stories high, and filled it with books, the number of letters would equal the number of stars we know today.
