Science Question for June

It's  a clear day, and Xavier is standing on a plateau in Wyoming. As he looks into the sky, an object about the size of the Starship Enterprise whizzes past at an altitude of 2640 feet above ground level and at the speed of light (300,000,000 meters per second). Xavier has 20-20 vision, and he is looking directly at the path of the Enterprise. What does he see?

Science Question for May

X wants to know what is the loudest noise that can be made using household devices. How would you measure the loudest noise you could make? The best answer will win a copy of Scientific American or Nuts and Volts. Explain your answer in the comment section.

There were 5 answers to the May science question, and congratulations to the winner, Edison Thomas, who gave a good answer, a practical measurement technique, and an environmentally conscious plan. Edison wins the September 2012 copy of Nuts and Volts magazine, featuring cool audio projects. The winner of the "Bonehead" prize is Rebel, who missed the point altogether. Thanks to all.

Science Question for April 2013

X is interested in the storage capacity of the human brain. It's probably unknown as to the ultimate capacity of the brain, but this April question is about something really possible.

Say you had 100,000 people from all 50 states, all adult age groups, all cultural backgrounds, all economic backgrounds, and they all had IQs of at least 100. Given a study period of 8 hours, how many digits of pi would each person be able to recite from memory? Say there was a really good prize for each person in the top 1% of reciters.

How many digits of pi do you think people in the winning 1% group could recite?
  • Overall champion __________ digits
  • Average of the 1% group__________digits
  • Lowest score in the 1% group__________digits

Briefly, how did you decide on your answers?

1. Assume you could drill a 2" diameter hole from your back yard down to the center of the Earth.
2. Assume you screw 995,406-21 foot lengths of 1" galvanized threaded pipe together using couplings, and let the assembly down the hole as you screw it together. You put a cap on the first pipe at the bottom end before letting it down in the hole.
