Here's How Schrodinger's Cat Works. Erwin Schrodinger was one of the key figures in quantum physics, even before his famous "Schrodinger's Cat" thought experiment.
He had created the quantum wave function, which was now the defining equation of motion in the universe, but the problem is that it expressed all motion in the form of a series of probabilities—something which goes in direct violation to how most scientists of the day (and possibly even today) like to believe about how physical reality operates. Schrodinger himself was one such scientist and he came up with the concept of Schrodinger's Cat to illustrate the issues with quantum physics. Let's consider the issues, then, and see how Schrodinger sought to illustrate them through analogy. Quantum Indeterminancy The quantum wave function portrays all physical quantities as a series of quantum states along with a probability of a system being in a given state.

Woodlands Maths Zone - Fun interactive maths games. Comparing decimal place value. Theconversation. Most people have heard of the mathematical constant Pi (π), and will know that it’s roughly 3.14.
Taking inspiration from these three digits, March 14 (3/14 in the US date format) is heralded as international Pi Day, first marked by US physicist Larry Shaw in 1988. This year brings a unique opportunity to demonstrate an entirely unnecessary degree of zeal by marking Pi Day correct to nine decimal places on March 14, 2015, at 9.26am 53sec – corresponding to 3.141592653, the first 10 digits of Pi. If you’re too busy this weekend, you could book in July 22 – another way of expressing Pi approximately is the fraction 22/7. Pi is calculated as the ratio between a circle’s circumference to its diameter. Pi is always the same value, no matter the size of the circle, which makes it an important mathematical constant. The ancient Babylonians calculated Pi as three by taking three times the square of the circle’s radius, later refining the value to 3.125. On Pi Day, Celebrate Math’s Enigmas.
Photo Manil Suri BALTIMORE — EACH year, March 14 is Pi Day, in honor of the mathematical constant.
Saturday is the once-in-a-century event when the year, ’15, brings the full date in line with the first five digits of pi’s decimal expansion — 3.1415. iZone NYC. A.

It took me a while to figure out what they did, but it's awesome. We've had some requests to explain how to do this and make it work, so using my super high tech Microsoft Paint program, I'll walk you through how to do this multiplication trick.
We'll start with multiplying single digits together. We'll do 3x4. I tried to "color code" each number (I'm sorry to those with color blindness, like my husband...the colors won't help a whole lot, I know). Start with the first number, 3. Next, go to your second number, 4. Now, you are looking for the intersections of the lines (where they cross): Count all the intersections, and you have your answer: So now, what about multiplying numbers with double digits? Start with the first digit of the first number. Now move on to the second digit in the first number. Maths Games for KS1.
