    Climate Emergency? Global Sea Ice at Anomalously Low Levels

    This week a plot showing the global sea ice over time went viral due to shockingly low levels, smashing previous records. The plot was so weird that we decided to check out the data for ourselves and see if it was legit. Indeed, we can reproduce this alarming plot and provide some links and scripts for any of you who want to go ahead and try yourselves. Here we get into why we think these kinds of weird observations may become more common in the future. ::More about this Video:: ► National Sea and Ice Data Center archive of sea ice extent data: https://nsidc.org/data/docs/noaa/g02135_seaice_index/ ► My Mathematica script used to generate a confirming plot: https://github.com/davidkipping/seaiceextent ► Two of the first tweets publicizing the viral plot, Zach Labe (https://twitter.com/ZLabe/status/798913080168095744) and Eric Holthaus (https://twitter.com/EricHolthaus/status/800067428419940352). ► Wipneus archive of plots: https://sites.google.com/site/arctischepinguin/home/sea-ice-extent-area/grf ► Eric Holthaus blog article about the viral plot: http://tinyletter.com/sciencebyericholthaus/letters/today-in-weather-climate-sea-ice-tipping-point-edition-monday-november-21th ► Guardian article on record Arctic temperatures: https://www.theguardian.com/environment/2016/nov/22/extraordinarily-hot-arctic-temperatures-alarm-scientists ► CNN article on record Arctic temperatures: http://www.cnn.com/2016/11/18/world/sea-ice-arctic-antarctic-lows/ ► Conrath at al.

    How Jeff Lawson Made $72 Billion Sending 6 Digit Codes | Logically Answered

    How Jeff Lawson Made $72 Billion Sending 6 Digit Codes Earn Cash Back On Stocks: Up To $5,000 Per Year https://www.silomarkets.com/logic In the modern era, onetime passcodes or OTPs are something that we’re all too familiar with. Their the pesky 6digit codes that we have to enter every time we log in or do some sort of sensitive task. But, while these codes are indeed annoying, they very much do protect our account and data security across our various online activities. And it turns out that offering these protections is a lot more valuable than you might think. A company called Twilio specializes in communications API mainly centered around sending OTPs, email verifications, shipping updates, and things of this nature. It wouldn’t be surprising to see such a company boast a valuation in the billions or even up to $10 billion but Twilio was actually boasting a peak valuation of over $70 billion. They have fallen quite a bit since that peak but they’re still worth over $12 billion. This video explains the story of Twilio and how they managed to make over $70 billion by sending OTP codes.

    How Working Less Could Solve Both Unemployment and Climate Change

    What if cutting your work week to 30 hours could actually create more jobs AND save the planet? Economist Juliet Schor has run the numbers, and the results might flip everything you think you know about productivity. In this episode, Alex Romano breaks down her research showing how Americans' obsession with working longer hours is making everyone miserable while destroying the environment. 🎯 What You'll Learn: • Why Germans work 400 fewer hours per year but report higher life satisfaction than Americans • The math behind how a 30-hour work week could eliminate unemployment completely • How your closet full of barely-worn clothes connects to climate change (spoiler: 70 pounds of waste per person annually) • The energy savings possible when we buy local food instead of shipping lettuce across continents 👤 Perfect for: lifelong learners and anyone passionate about personal growth who's ever wondered if there's a smarter way to organize society than our current "work until you drop" culture. 📍 Chapters: [00:00] Alex Romano introduces the radical idea that less work equals more prosperity [02:15] Breaking down the American vs. German work-life balance experiment [04:30] The unemployment solution hiding in plain sight [06:45] Why we throw away perfectly good stuff and what it costs the planet [08:30] Local food systems and the 90% energy reduction you've never heard about [10:15] Practical steps to start working less while living better Schor's research suggests we've been asking the wrong question. Instead of "how do we create more jobs?" maybe we should ask "how do we share the work we already have?" The answers might surprise you, especially when you see how much happier people become when they stop chasing stuff and start valuing time. 🔔 Never miss an episode: Follow Curious Machines on Spotify and turn on notifications.

    Does Life Need a Multiverse to Exist?

There we go - one hopefully uncontroversial statement. Therefore our universe is capable of producing and supporting life. How am I going? Two for two? Let’s try for three: therefore there are countless universes. Hmmm. Did I break my streak? Hosted by Matt O'Dowd Written by Matt O'Dowd Graphics by Leonardo Scholzer & Adriano Leal Directed by: Andrew Kornhaber Executive Producers: Eric Brown & Andrew Kornhaber End Credits Music by J.R.S. Schattenberg: https://www.youtube.com/channel/UCRl6-nb4iOnsij-vnpAjp0Q Our universe seems to operate according to a set of fundamental rules that we try to understand and model with the equations of our laws of physics. Those equations always include one or more fundamental constants - simple numbers that set the scale for the equation. We can’t determine the values of these constants from pure theory - we have to measure them in the real universe. These are things like the speed of light, the Planck constant, the masses of the elementary particles, and the constants defining the relative strengths of the fundamental forces - the so-called coupling constants.
