In ‘Unreported World’ we’re in the Congo with a tribe under threat, as the forest they hunt for food in is put off limits to protect the wildlife. The Baka tribe tell us of threats and intimidation by the proposed park’s guards who are part-funded by the World Wildlife Fund.

Ade Adepitan travels deep into the rainforests to see how the Baka are fighting for food. Is the survival of endangered species being put above their own?

WARNING: You may find scenes of
butchered animals upsetting.

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.

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

Easy to understand animation explaining all basic concepts.

Exponential Growth

Paul Andersen explains how populations eventually reach a carrying capacity in logistic growth. He begins with a brief discussion of population size ( N ), growth rate ( r ) and exponential growth. He then explains how density dependent limiting factors eventually decrease the growth rate until a population reaches a carrying capacity ( K ). A mathematical simulation of this process is included along with a brief discussion of r and K selected species.
