The friendship recession | Richard Reeves
Richard Reeves, a senior fellow at the Brookings Institution, discusses the importance of friendships and the potential “friendship recession.” He notes that loneliness can be as harmful as smoking 15 cigarettes per day, but measuring and quantifying friendships is difficult. According to Reeves, an ideal number of close friends is around three or four. But […]
Train for any argument with Harvard’s former debate coach | Bo Seo
Bo Seo, an author and two-time world debate champion, believes our public conversations are in crisis. To Seo, our arguing skills have collectively atrophied over recent decades, resulting in bad arguments that have caused many people to lose faith in the idea that productive disagreements are even possible. That’s why Seo suggests a framework called […]
Microquasar SS 433 – Relativistic jets accelerating particles to extreme energies inside our Galaxy
SS 433 stands out as one of the most intriguing objects within our Milky Way. At its core, a black hole draws material from a closely orbiting companion star, creating a hot accretion disk. Notably, a pair of oppositely directed beams of plasma («jets») spirals away perpendicularly from the disk’s surface at just over a […]
Don’t chase happiness. Become antifragile | Tal Ben-Shahar | Big Think
Antifragility is the idea of putting pressure on a system, or human, the system or human actually grows bigger and stronger. Antifragile systems are all around us. One example of this is our muscular system. We go to the gym to lift weights. By doing so we are putting pressure on our system to help […]

La bacteria causante de la sífilis se hallaba en América al menos mil años antes de la llegada de Colón
Agencia SINC Uno de los mayores misterios en la historia de las epidemias es si la sífilis fue introducida en Europa tras el primer viaje de Colón a las Américas. Ahora, un estudio, liderado por la Universidad de Basilea (Suiza), ha confirmado la presencia de una de las enfermedades treponematósicas, llamada bejel (enfermedad similar a la sífilis), […]
Change Your Life – One Tiny Step at a Time
If you are like most people, there is a gap between the person you are and the person you wish to be. There are little things you think you should do and big things you ought to achieve. From working out regularly, eating healthy, learning a language, working on your novel, reading more or simply […]

Cosine: The exact moment Jeff Bezos decided not to become a physicist
Jeff Bezos on why he realized he would not become a theoretical physicist
4.5 Billion Years in 1 Hour
Earth is 4.5 billion years old – which is approximately the same amount of time it took us to create this video. We’ve scaled the complete timeline of our Earth’s life into our first animated movie! Every second shows about a million years of the planet’s evolution. Hop on a musical train ride and experience […]
Can a New Law of Physics Explain a Black Hole Paradox?
When the theoretical physicist Leonard Susskind encountered a head-scratching paradox about black holes, he turned to an unexpected place: computer science. In nature, most self-contained systems eventually reach thermodynamic equilibrium … but not black holes. The interior volume of a black hole appears to forever expand without limit. But why? Susskind had a suspicion that […]
Could One Physics Theory Unlock the Mysteries of the Brain?
The ability of the phenomenon of criticality to explain the sudden emergence of new properties in complex systems has fascinated scientists in recent decades. When systems are balanced at their “critical point,” small changes in individual units can trigger outsized events, just as falling pebbles can start an avalanche. That abrupt shift in behavior describes […]
A Surprising Thing Happens When Two Black Holes Slam Together
What is the «chirp»? And why is it important to astronomers? Some of the most violent cosmic collisions in the universe occur silently in the vacuum of space, but with the right instrumental ears, we can still hear it happen. Here’s how.
