Rompecabezas redondos de la Luna, la Tierra y algunos planetas

Hace unas semanas buscando puzzles para matar el aburrimiento encontré estos curiosos puzzles redondos de 1.000 piezas en AliExpress. No tengo ni idea de cómo será su calidad ni si separecerán mucho a las fotos, porque comprar allí siempre supone un pequeño salto de fe, pero ahí quedan. Cuestan unos 9 ó 10 euros + gastos de envío.

Además del diseño con la foto lunar hay otros con la Tierra, en distintas vistas: Europa y Australia. También hay otro con las imágenes de Júpiter, Venus y Marte, a cuál más complicado. Marte parece el más difícil porque es el que menos zonas distintas parece tener a simple vista.

Lo que no tengo muy claro es si luego será fácil encontrar marcos apropiados si quieres conservarlos una vez resueltos.

Rocket Lab sufre el primer fallo de un cohete Electrón

Esta pasada noche Rocket Lab ha sufrido el primer fallo de un cohete Electrón desde su entrada en servicio. En concreto era el Electrón número 13 que lanzaban, lo que no deja de ser una lamentable coincidencia.

Todo fue bien durante los primeros minutos del lanzamiento. De hecho todo fue bien hasta unos minutos después del separamiento de la primera y la segunda etapas. Pero a los 5:40 del despegue la imagen de vídeo se quedó congelada, lo que no tendría que ser un problema per se. Sin embargo poco después de los seis minutos la altitud del cohete, tras alcanzar un máximo de 192,8 kilómetros, comenzó a descender sin parar, algo que definitivamente no quieres ver en el lanzamiento de un cohete.

En un principio Rocket Lab dijo que se había perdido la señal de vídeo pero que seguían recibiendo telemetría delcohete, así que seguirían dando actualizaciones a través de sus redes sociales. Pero poco después tuiteaban reonociendo que habían perdido el cohete y su carga útil.

En este caso se trataba del CE-SAT 1B de Canon, el Faraday 1 de In-Space Missions y cinco Flock-4e de Planet Labs. Como seis de los siete satélites que iban a bordo estaban destinados a obtener imágenes de nuestro planeta el cohete había sido bautizado Pics Or It Dind't Happen (Fotos o no pasó).

No está clara todavía la causa del fallo pero se especula con que ha podido tener que ver con un fallo en el cambio de las baterías de la segunda etapa del cohete. El Electrón, a diferencia de otros cohetes que usa turbobombas impulsadas por gas para mover los propelentes de los depósitos al motor, usa turbobombas eléctricas. Y un truco que usa es que cuando las dos primeras baterías se agotan las expulsa para ahorrar peso. Claro que antes ha de activar una tercera batería que es la que se encarga de mover los propelentes hasta la separación de la tercera etapa. Pero sin batería no hay flujo de propelentes, luego no hay motor en funcionamiento, luego no hay empuje.

Es la primera vez que falla el lanzamiento de un Electrón por un fallo del cohete. Hasta ahora sólo el primer Electrón, lanzado el 25 de mayo de 2017, había fallado a la hora de entrar en órbita. Pero fue por un fallo en la configuración de los equipos de tierra, no por un fallo del cohete. De hecho no huno que hacer ningún cambio en el cohete para el segundo lanzamiento, que se llevó a cabo sin problemas el 21 de enero de 2018.

A Rocket Lab le toca ahora investigar qué ha pasado e implementar los cambios que sean necesarios. Y aunque poner cohetes en órbita diste de ser rutinario este fallo llega en un momento en el que la empresa estaba en un momento realmente dulce: con un lanzamiento con éxito tras otro y dos nuevas plataformas de lanzamiento a punto de entrar en servicio y superada la interrupción causada por el coronavirus su intención era mantener un ritmo de un lanzamiento al mes durante el resto de 2020 y el principio de 2021 pero ya no va a poder ser.

En cualquier caso es una de las empresas que está revolucionando el acceso al espacio con lanzamientos frecuentes y con poco tiempo de espera.

El Centro para el Estudio de los Riesgos Existenciales y los diversos «fines del mundo» de la Universidad de Cambridge

En la Universidad de Cambridge tienen un curioso departamento dedicado podríamos decir al análisis de diversas versiones del fin de mundo, apropiadamente llamado

• Centro para el Estudio de los Riesgos Existenciales (CSER)

Estos riesgos existenciales para la raza humana los han dividido en cuatro, que son básicamente eventos de baja probabilidad pero alto impacto, entre ellos:

• Riesgos tecnológicos extremos
• Riesgos biológicos catastróficos globales
• Riesgos extremos relacionados con el colapso del ecosistema
• Riesgos asociados a la Inteligencia Artificial

Cada apartado tiene interesantes contenidos y apuntes sobre qué tipo de eventos producirían estos problemas catastróficos: desde una inteligencia artificial controlando las armas militares y causando un desastre global por error al colapso del ecosistema debido a la emergencia climática global en que estamos inmersos o a una pandemia que borre a los seres humanos del mapa.

Para no verlo todo negativfo y ser un poco positifvos el CSER también se dedica a preparar trabajos y vídeos acerca de cómo mitigar o minimizar estos riesgos. Entre otros están cómo hacer que las IA sean más fiables, cómo conservar las semillas para que sobrevivan a un posible escenario apocalíptico y cosas así. Tranquiliza saber que al menos hay alguien pensando en todo esto.

If you’re over 75, catching covid-19 can be like playing Russian roulette

Are you hiding from covid-19? I am. The reason is simple: the high chance of death from the virus. 

I was reminded of the risk last week by this report from the New York City health department and Columbia University which estimated that on average, between March and May, the chance of dying if you get infected by SARS-CoV-2 was 1.45%.

That’s higher than your lifetime chance of getting killed in a car wreck. That’s every driver cutting you off, every corner taken too fast, every time you nearly dozed off on the highway, all crammed into one. That’s not a disease I want to get. For someone my mother’s age, the chance of death came to 13.83% but ranged as high as 17%. That’s roughly 1 in 6, or the chance you’ll lose at Russian roulette. That’s not a game I want my mother to play.

The rate at which people are dying from the coronavirus has been estimated many times and is calculated in different ways. For example, if you become an official covid-19 “case” on the government’s books, your death chance is more like 5%, because you’re sick enough to have sought out help and to have been tested. 

But this study instead calculated the “infection fatality ratio,” or IFR. That’s the chance you die if infected at all. This is the real risk to keep in view. It includes people who are asymptomatic, get only a sniffle, or tough it out at home and never get tested. 

Because we don’t know who those people who never got tested are, IFR figures are always an estimate, and the 1.45% figure calculated for New York is higher than most others, many of which fluctuate around 1%. That could be due to higher rates of diabetes and heart disease in the city, or to estimates used in the study. 

It’s also true that your personal odds of dying from covid-19 will differ from the average. Location matters—cruise ship or city—and so do your sex, your age, and whether you have preexisting health conditions. If you’re in college, your death odds are probably lower by a factor of a hundred, though if you’re morbidly obese, they go back up. Poor health—cancer, clogged arteries—also steeply increase what scientists call the “odds ratio” of dying. 

The biggest factor, though, is age.  I looked at the actuarial tables, and the chance of death for a man in my age group (I’m 51) is around 0.4% per year from all causes. So if I get covid-19, my death chance is probably three times my annual all-cause annual risk (since I am a man, my covid-19 risk is higher than the average). Is that a chance I can live with? Maybe, but the problem is that I have to take that extra risk right now, all up front, not spread out over time where I can’t see or worry about it. 

Tbh, these % don’t help me. More useful would be a list of comparable risks associated with common behaviours that I uncritically accept. Do you know of any examples?

— Andrew Harmer (@andrew_harmer) July 1, 2020

On Twitter, some readers complained that average risks don’t tell them much about how to think or act. They have a point. What’s a real-life risk that’s similar to a 1.45% chance of dying? It wasn’t easy to think of one, since mathematically, you can’t encounter such a big risk very often. Skydiving, maybe?  According to the US Parachute Association, there’s just one fatality for every 220,301 jumps. It would take 3,200 jumps to equal the average risk of death from covid. 

Risk perceptions differ, but it’s the immense difference in IFR risk for the young (under 25) and the elderly (over 75) that really should complicate the reopening discussion. Judging from the New York data, Grandpa’s death chances from infection are 1,000 times that of Junior. So yes, we need schools to keep kids occupied, learning, and healthy. And for them, thank goodness, the chances of death are very low. But reopening schools and colleges has the ugly side effect that those with the lowest risk could be, in effect,  putting a gun to the head of those with the highest (although there is still we do not know about how transmissible the virus is among children).

Decent odds

The virus is now spreading fast again in the US, after the country failed to settle on a strong mitigation plan. At the current rate of spread—40,000 confirmed cases a day (and maybe five to 10 times that in reality)—it’s only two years until most people in the US have been infected. It means we’re pointed toward what, since the outset, has been seen as the worst-case scenario: a couple of hundred million infected and a quarter-million deaths. 

By now you might be wondering what your own death risk is. Online, you can find apps that will calculate it, like one at covid19survivalcalculator.com, which employs odds ratios from the World Health Organization.  I gave it my age, gender, body mass index, and underlying conditions and learned that my overall death risk was a bit higher than the average. But the site also wanted to account for my chance of getting infected in the first place. After I told it I was social distancing and mostly wearing a mask, and my rural zip code, the gadget thought I had only a 5% of getting infected. 

I clicked, the page paused, and the final answer appeared: “Survival Probability: 99.975%”. 

Those are odds I can live with. And that’s why I am not leaving the house.
