Black holes may hold the key to understanding the most fundamental truths of the universe, but how do you see something that’s, well, black? Astronomers think they have the answer. Thanks to a global array of radio telescopes that turn the Earth into a giant receiver, we may soon have the first picture of the event horizon of Sagittarius A*, the black hole at the center of the Milky Way galaxy. And, with the power of math, scientists are going even further, using equations to “look” inside black holes, peering at the central singularity where general relativity and quantum mechanics collide. Join Brian Greene and other leading physicists and astronomers on a journey to make darkness visible.

Electromagnetism Explained.

Arithmetic Progression (AP) and Geometric Progression (GP) - Both super important concepts explained in this video. ⁣To summarise, An arithmetic Progression is a sequence with the difference between two consecutive terms constant. And a geometric Progression is a sequence with the ratio between two consecutive terms constant.


⁣In this video, we will learn:
0:00 Arithmetic Sequence
0:41 nth Term of Arithmetic Sequence
1:20 Average of n Terms in Arithmetic Sequence
1:34 Sum of Terms in Arithmetic Sequence
2:38 Geometric Sequence or Progression
4:11 nth Term of Geometric Sequence
4:16 Sum of Terms in Geometric Sequence

Professor Eric Laithwaite (1921-1997) of Imperial College London demonstrates the difference between magnetic and electro-magnetic motors. Examples futuristic - include minute pump that can fit inside human tissue and a huge test rig to help develop high speed vehicles driven by a linear motor.

This is one of a series of 16mm colour films made for schools. They were all made in Eric Laithwaite's "Heavy Electrical Laboratory" in the Electrical Engineering Department at Imperial College London.

Yvan Sagnet from Cameroon is battling modern slavery in Italy's agricultural sector. Sagnet once worked as a low-wage farmhand. Now he is fighting for the rights of seasonal farmworkers, taking criminal recruiters, or gangmasters, to court.

Yvan Sagnet calls them slaves: the hundreds of thousands of seasonal farmworkers from Africa and eastern Europe on Italy's fields. Without their labor the country would have no tomato, orange or olive harvest. But the workers are exploited and often forced to live under inhumane conditions in ruins or shanty towns called ghettos. In 2011 Sagnet himself briefly picked tomatoes on the fields near the southern Italian town of Nardò. For four days he labored to fill the 350-kilogram crates. He earned 14 euros a day, ten of which he had to hand over to the gangmaster, or Caporale, for transport and water. Caporale is the term for the criminal recruiters who control and exploit the workers. After a 14-hour day working under the blazing sun and even being beaten, Sagnet took home only four euros. He helped to organize the first strike among the farmhands. It was a success, and since then he has been an activist for the rights of the farmworkers and against the gangmasters. Despite death threats, he has set up an organization called NoCap, a label to certify produce farmed under ethically acceptable conditions. And he has taken his fight against exploitation and slavery to the courts. So far, the Italian justice system has responded slowly. It's a fight that will take a long time to win.
