@AutopistasUraba Hola, hay alguna novedad? Saludos!

Sam and I are shocked and saddened by what the board did today. Let us first say thank you to all the incredible people who we have worked with at OpenAI, our customers, our investors, and all of those who have been reaching out. We too are still trying to figure out exactly what happened. Here is what we know: - Last night, Sam got a text from Ilya asking to talk at noon Friday. Sam joined a Google Meet and the whole board, except Greg, was there. Ilya told Sam he was being fired and that the news was going out very soon. - At 12:19pm, Greg got a text from Ilya asking for a quick call. At 12:23pm, Ilya sent a Google Meet link. Greg was told that he was being removed from the board (but was vital to the company and would retain his role) and that Sam had been fired. Around the same time, OpenAI published a blog post. - As far as we know, the management team was made aware of this shortly after, other than Mira who found out the night prior. The outpouring of support has been really nice; thank you, but please don’t spend any time being concerned. We will be fine. Greater things coming soon.

@Devimar_SAS Hola. ¿Hay alguna novedad sobre el cierre? ¿Tienen un tiempo estimado de cuando se podría abrir la vía? Gracias

@AutopistasUraba buenas noches. Podrían, por favor, informarme cómo está el trayecto Urabá-Medellín? Gracias!

@AutopistasUraba ¡hola! Podrían, por favor, compartirme el estado de la vía Medellín-Urabá? Saludos!

¿De verdad no le prestaron atención a Petro en la Asamblea de la ONU? Antes de comenzar su intervención en la Asamblea de las Naciones Unidas, el presidente Gustavo Petro tuvo que esperar unos minutos por el ruido en la sala. ¿Qué pasó en realidad? En este video se lo explicamos en detalle. bit.ly/3LrnwDO ‣ @josebaezg

First independent measurement of zero resistance in LK-99 A team of scientists from the Physics Department of Southeast University, a top university in Nanjing, China, have reported measuring 0 resistance in a sample of LK-99 they synthesized from scratch. Here is the video: - They measure 0 resistance at 110K (-163C) using the four-point probe method. 0 resistance at this high of a temperature at ambient pressure is a new discovery in materials science - They also claim a transition in and out of zero resistance state depending on a strongly applied magnetic field - a classic characteristic of superconductivity. - The sample they synthesized is reported to have much higher purity than the original Korean team of LKK - They note an interesting and abrupt drop in resistance, by several orders of magnitude, between ~300 and 220K (approx values from the graph). This is currently unexplained, but is in rough agreement with LKK - i.e., LKK may have been measuring this higher-temperature 'drop' which was two orders of magnitude. - They retain the claim that this is not absolute conclusive proof of superconductivity, but it is suggestive of very interesting electronic properties in this material. These results compare nicely with recent simulations out of Lawrence Berkeley National Lab, University of Boulder Colorado, Shenyang National Laboratory, and TU Wien, all performed by high profile and established materials scientists. Those simulations have converged on LK-99 having the potential for superconductivity at high temperatures and ambient pressures due to the formation of flat energy bands when lead-apatite crystal is doped with copper. Notably, other doping metals may also achieve similar or better performance. Here is a summary of those simulations: x.com/andercot/statu…

In 2 days there are have been 4 studies that help explain LK-99's potential superconducting abilities. These simulations converge on key properties that suggest a new class of SC materials, and help explain quirks of TK-99 we've seen so far. Here is the easy-to-digest summary

¡Tenemos una gran noticia! A partir del 9 de noviembre de 2022, los nacionales 🇨🇴 no necesitarán una visa de visitante para viajar al 🇬🇧 por periodos de hasta 6 meses. Visita 👉gov.uk/standard-visit… para revisar toda la información. ¡Reino Unido los está esperando! #UKCOL

Pasamos de reírnos del presidente a reírnos con el presidente.

Hoy nace la política integral de seguridad humana por la paz y la defensa de la vida en los territorios. Un compromiso del presidente @petrogustavo para dar solución a los problemas de violencia a través de una articulación de diversas entidades del Estado. #ComienzaTuGobierno

Acerca del impuesto a las bebidas azucaradas contemplado en la #ReformaTributaria, el presidente @petrogustavo destacó que esta iniciativa busca proteger la salud y el bienestar de la población, para garantizar que nuestro país sea #PotenciaMundialDeLaVida

El Gobierno de Iván Duque ha terminado.

Escuchamos el himno de una nueva Colombia. Una potencia de la vida #ComienzaTuGobierno.

It's here–the deepest, sharpest infrared view of the universe to date: Webb's First Deep Field. Previewed by @POTUS on July 11, it shows galaxies once invisible to us. The full set of @NASAWebb's first full-color images & data will be revealed July 12: nasa.gov/webbfirstimages

“Alí, ya no nos pueden decir que no podemos”: Francia Márquez. ¡Gracias mana!

—¿Le ofrezco un café, expreso? —Doctor Petro, no más.

Gracias @FranciaMarquezM, primera Vicepresidenta Afro colombiana, quién hace historia por su compromiso con la igualdad, justicia climática, derechos de las mujeres, Afrodescendientes y personas excluidas!Trabajaremos juntas para avanzar en un mundo nuevo de paz, amor y justicia!

Acabo de tener mi primera reunión con @epsycampbell Vicepresidenta de Costa Rica y la primera mujer afrodescendiente en ocupar este alto cargo en el continente. Hablamos sobre desafíos en la región, trabajaremos en la paz, la justicia racial, la justicia climática y de género.

Hoy recibimos la credencial de vicepresidenta. Cumpliremos el compromiso con nuestro pueblo. ✊🇨🇴💪❤️
