Tangled Earphones Science Studies

Tangled Earphones Science Studies

A group of physicists have finally undertaken to resolve the mystery as to why earphones, and other ropey things, tangle reports DiscoverMaganize.com.

They put strings of different stiffness in a box and tumbled it.

Complex knots form within seconds with the stiffer strings less likely to get knotted.

They made computer simulations of the data obtained and learned that when jostled the strings formed coils with the loose end weaving through the strands like a grandma knitting a sweater.

The scientists say the knots were analyzed using mathematical knot theory.

Betcha didn’t even know there was such a thing as mathematical knot theory.

Keystone Exam Change Would Empower Districts

Joanne Yurchak reports that a bill has been introduced in the Pennsylvania Senate that would remove the Keystone Exams as a graduation requirement and  allow school districts to determine for themselves how their results may be used.

The bill, SB 1450, was introduced Wednesday, June 25 by Mike Folmer (R-48). It has eight co-sponsors including Senate Majority Leader Dominic Pileggi (R-9) and Ted Erickson (R-26).

Thank these men.

The Keystone Exams have been made part of Pa Core Standards, which is the window dressing for the implementation in the Commonwealth of the  Common Core educational standard being pushed by the plutocrats.
