"It's not really about physics. It's about money and marketing. Adidas is selling the official ball to the public for $ 160 to $170. "Meht a agrees that we don't need to spend all that money for an official football. The old one you've got in the supermarket is just as good....
Their movement is called sidewinding.Daniel Goldman works as a physics teacher atthe Georgia Institute of Technology in Atlanta. Hesays the snakes moved easily in the sand—evenwhen the sand began moving.We noticed that the animals were in factsidewinding, using the same kind of pattern of...
A basic type of problem that occurs throughout mathematics is the lifting problem: given some space that “sits above” some other “base” space due to a projection map , and some map from a third space into the base space , find a “lift” of to , that is to say a map such tha...
What is the divisibility rule of 11? Using Fermat s Little Theorem, show that 2^{56}+3^{56} is divisible by 17. There is a famous irrational number called euler's number, often symbolized with an e. Like pie it never seems to end. The first few digits of e are 2.7182818284. Betwe...
What is the relation between mathematical logic and set theory? what is the definition of mean in algebra ? In this algebraic expression, what is 3 called: 6n + 3 How to show a function is an isomorphism? What is a tensor in mathematical physics?
One of the major physics forums has an annoying policy of an absolute ban on free-energy discussions, including ones like "Can someone explain to me why this alleged free-energy device doesn't do what it claims?". This is really annoying because it's one of the few forums that has ...
We perform a bordism computation to show that the E_{7(7)}({\mathbb {R}}) U-duality symmetry of 4d {\mathcal {N}} = 8 supergravity could have an anomaly invisible to perturbative methods; then we show that this anomaly is trivial. We compute the relevant bordism group using the Ada...
The number theorist Andrew, Tom from the physics department, Marc from computer science, and Dayna, a differential-equations specialist, were watching them intently. When Fortune turns around and notices them, they apologize for disturbing and hurry off. Footnote 24 Preston:: That’s a very ...
The brain consists of some 100 billion nerve cells (give or take a few bil- lion). Each cell is connected to thousands of other nerve cells in an astonishingly complex network. In scientific terms, the brain is sometimes called 'the final frontier,' because its function is still not ...
