Education: How Common Core Failed In U.S. Schools

First implemented in 2009, Common Core was an ambitious initiative to revolutionize the American education system. National leaders from Bill Gates to President Obama supported the idea and it cost an estimated $15.8 billion to implement. Years later, research showed the new curriculum had minimal impact on student performance. So why did Common Core fail? Can a common curriculum be successful for all students? Watch the video to find out.

Seabirds: Scientists Save Black-Footed Albatross From Rising Sea Levels

Most black-footed albatross nest on sandy beaches in Hawaii—but rising sea levels threaten their eggs and chicks. Researchers in Mexico and the United States came up with a way to save these birds: having young albatross hatch and imprint on an island 6000 kilometers away with higher ground. Watch to see the journey of these black-footed albatross. Read the story: https://www.sciencemag.org/news/2021/…

Science: Rise Of ‘Exascale Supercomputers’ (Video)

The next generation of computing is on the horizon, and several new machines may just smash all the records…with two nations neck and neck in a race to get there first.

The ENIAC was capable of about 400 FLOPS. FLOPS stands for floating-point operations per second, which basically tells us how many calculations the computer can do per second. This makes measuring FLOPS a way of calculating computing power. So, the ENIAC was sitting at 400 FLOPS in 1945, and in the ten years it was operational, it may have performed more calculations than all of humanity had up until that point in time—that was the kind of leap digital computing gave us. From that 400 FLOPS we upgraded to 10,000 FLOPS, and then a million, a billion, a trillion, a quadrillion FLOPS. That’s petascale computing, and that’s the level of today’s most powerful supercomputers. But what’s coming next is exascale computing. That’s zeroes. 1 quintillion operations per second. Exascale computers will be a thousand times better performing than the petascale machines we have now. Or, to put it another way, if you wanted to do the same number of calculations that an exascale computer can do in ONE second…you’d be doing math for over 31 billion years.

Tropical Travel: ‘The Hawaiian Islands’ (Video)

The Hawaiian Islands are an archipelago of eight major islands, several atolls, numerous smaller islets, and seamounts in the North Pacific Ocean, extending some 1,500 miles from the island of Hawaiʻi in the south to northernmost Kure Atoll.
