Number crunching
Wednesday, August 30th, 2006What is both rare and everywhere?
- Uranium is rare, but everywhere.
One ton of an ordinary rock, such as granite, contains 16g of Thorium and Uranium.
A kilogram of Uranium is equivalent to 20,000 tons of TNT, which is approx. the same as the energy potential of 20,000 tons of gasoline.
One ton of common-or-garden rock contains the equivalent fuel of 320 tons of gasoline. It could take a lot less than that to extract it.
Until recently, what did environmentalists and Car/Oil companies have in common?
- A reason to hate nuclear power.
It used to be very easy to make a case against nuclear energy, and if you are either a treehugger or a oil exec. you would be historically allied.
Dolphins are not intelligent.
Sunday, August 20th, 2006Dolphins have had a rough time lately, they used to be considered intelligent and kind - then researchers pointed out that they gang rape females to death when mating.
Now it turns out they they may not even be intelligent. In fact they may be not be much smarter than a goldfish.
Their big brains are mostly fat with very few neurons.
Compound interest rates.
Thursday, August 17th, 2006Want to work out compound interest rates in your head?
Use the Rule of 72
ln 2 is 69.3% - which is approximately equal to 70 which is close to 72 - which has many factors making it easy to do mental division.
So to work out compound interests rates’ doubling times divide 72 by the Interest rate.
At 6% $100 becomes $200 in 72/6 = 12 years
A chicken cost $150 in the medieval era, today’s $2 chickens must be medievally bad.
Wednesday, August 2nd, 2006I just saw an ad for a whole roast chicken - for under $2. $2 to raise, kill, prepare and cook an animal. So I did some research to see just how insanely cheap mechanized farming produce has become.
In the middle ages, an unplucked, unroasted chicken cost 5/8 of the daily wage of a master mason. This was a very highly paid and esteemed position for the day, but lets be conservative and assume that the equivalent would be someone on a current US salary of $60K per annum.
This would mean that a chicken cost around $150.
Gives some kind of perpective on what pumping oil into the ground and hormones into mammals can do.
The site below has some really interesting data on medieval food.
