Climate: The Empire State Building’s Green Upgrade

Energy usage by large, old buildings like the Empire State Building represents a huge obstacle to cities’ dreams of carbon neutrality. New York City’s buildings account for 70% of its carbon emissions, for example, and half of those emissions are produced by the largest 5% of its structures. But retrofitting old buildings to make them more energy efficient represents a formidable challenge, both from an engineering perspective and in terms of convincing owners that doing so is in their financial interest.

Climate Views: Rising High Water Levels In Kenya’s Great Rift Valley (Video)

In Kenya’s Rift Valley, climate change has brought an unprecedented increase in annual rainfall over the past several years, drowning pastureland, farms, homes, schools, churches, clinics and businesses.

The Great Rift Valley is part of an intra-continental ridge system that runs through Kenya from north to south. It is part of the Gregory Rift, the eastern branch of the East African Rift, which starts in Tanzania to the south and continues northward into Ethiopia.[1] It was formed on the “Kenyan Dome” a geographical upwelling created by the interactions of three major tectonics: the Arabian, Nubian, and Somalian plates.[2] In the past, it was seen as part of a “Great Rift Valley” that ran from Madagascar to Syria. Most of the valley falls within the former Rift Valley Province.

Science: Optical Atomic Clocks Redefine Time, Astronomer Vera Rubin

A web of three optical atomic clocks show incredibly accurate measurements of time, and the trailblazing astronomer who found hints of dark matter.

In this episode:

00:44 Optical clock network

Optical atomic clocks have the potential to reach new levels of accuracy and redefine how scientists measure time. However, this would require a worldwide system of connected clocks. Now researchers have shown that a network of three optical clocks is possible and confirm high levels of accuracy.

11:26 Vera Rubin

Vera Rubin was an astronomer whose observations were among the first to show evidence of dark matter. At the time, female astronomers were a rarity, but Vera blazed the trial for future women in science.

Music: South Korean Boy Band “BTS” – Time Magazine ‘Entertainer Of The Year’

BTS is TIME’s 2020 Entertainer of the Year. Between releasing multiple albums and breaking every type of record in 2020, the Korean pop band ascended to the zenith of pop stardom. In an era marked by so much anguish and cynicism, BTS has stayed true to their message of kindness, connection and self-acceptance. Tune in for a special performance from BTS tonight at 10/9c on NBC.

BTS, also known as the Bangtan Boys, is a seven-member South Korean boy band that began formation in 2010 and debuted in 2013 under Big Hit Entertainment. The septet—composed of RM, Jin, Suga, J-Hope, Jimin, V, and Jungkook—co-writes and co-produces much of their own output. 

Books: “The Clock Mirage – Our Myth Of Measured Time” By Joseph Mazur

The Clock Mirage - Our Myth of Measured Time - Joseph Mazur - Book Review - July 2020With a narrative punctuated by personal stories of time’s effects on truck drivers, Olympic racers, prisoners, and clockmakers, Mazur’s journey is filled with fascinating insights into how our technologies, our bodies, and our attitudes can change our perceptions. Ultimately, time reveals itself as something that rides on the rhythms of our minds. The Clock Mirage presents an innovative perspective that will force us to rethink our relationship with time, and how best to use it.

A tour of clocks throughout the centuries—from the sandglass to the telomere—to reveal the physical, biological, and social nature of time.

Wall Street Journal Review

What is time? This question has fascinated philosophers, mathematicians, and scientists for thousands of years. Why does time seem to speed up with age? What is its connection with memory, anticipation, and sleep cycles?

Award‑winning author and mathematician Joseph Mazur provides an engaging exploration of how the understanding of time has evolved throughout human history and offers a compelling new vision, submitting that time lives within us. Our cells, he notes, have a temporal awareness, guided by environmental cues in sync with patterns of social interaction. Readers learn that, as a consequence of time’s personal nature, a forty‑eight‑hour journey on the space shuttle can feel shorter than a six‑hour trip on the Soyuz capsule, that the Amondawa of the Amazon do not have ages, and that time speeds up with fever and slows down when we feel in danger.
