Moon “bombing”

Nasa has just “bombed” the Moon with two artificial meteorites in an attempt to see whether there is lunar water. This happened in the early hours of Saturday 10 October our time. Read about it here.

It looks like this venture has failed. What they were trying to do was created a huge plume of debris for analysis, but the impact was insufficient, according to this article.

Albert Einstein’s riddle

ALBERT EINSTEIN WROTE THIS RIDDLE EARLY DURING THE 19th CENTURY. HE SAID THAT 98% OF THE WORLD POPULATION WOULD NOT BE ABLE TO SOLVE IT.

ARE YOU IN THE TOP 2% OF INTELLIGENT PEOPLE IN THE WORLD? SOLVE THE RIDDLE AND FIND OUT.

There are no tricks, just pure logic, so good luck and don’t give up.

1. In a street there are five houses, painted five different colours.
2. In each house lives a person of different nationality
3. These five homeowners each drink a different kind of beverage, smoke different brand of cigar and keep a different pet.

THE QUESTION: WHO OWNS THE FISH?

HINTS

1. The Brit lives in a red house.
2. The Swede keeps dogs as pets.
3. The Dane drinks tea.
4. The Green house is next to, and on the left of the White house.
5. The owner of the Green house drinks coffee.
6. The person who smokes Pall Mall rears birds.
7. The owner of the Yellow house smokes Dunhill.

The Periodic Table gets a new element…

Element number 112 has just been discovered. See here for details. At the bottom of the webpage there is an opportunity for you to help name this new element. Have a go, please. Email me your ideas as well - each valid idea with a reasonable explanation wins one point.

Week 8 is nearly upon us - this is the latest you can hand in your Science Fair

For three points….

Which letter of the alphabet is used nowhere in the periodic table???

The Shocking History of Phosphorus or Fire from Urine

More than 300 years ago, in 1669, Hennig Brand, a Hamburg alchemist, like most chemists of his day, was trying to make gold. He let urine stand for days in a tub until it putrified. Then he boiled it down to a paste, heated this paste to a high temperature, and drew the vapours into water where they could condense - to gold. To his surprise and disappointment, however, he obtained instead a white, waxy substance that glowed in the dark. Brand had discovered phosphorus, the first element isolated other than the metals and non-metals, such as gold, lead and sulphur, that were known to the ancient civilisations. The word phosphorus comes from the Greek and means light bearer.

The Monty Hall Maths Problem

Sorry, guys, there has not been much to add in this difficult week. However, I’d like to share with you a really interesting mathematical probability problem brought to my attention by Caleb in my Year 12 Chemistry class. Click here to watch. Watch it a couple of times, please - it’s quite hard to get your head around.

Year 9 students might like to try to prove/disprove this problem for Science Fair. Try using shoe boxes instead of doors, and no goats please…

Thanks, Caleb, we all had a really interesting experience, though I know a number of us are still contemplating this.
