Cela fait longtemps que je n'ai pas profité des murs carrelés dans les climats chauds...

It's been a while since I enjoyed tiled walls in warm climates....

Ha pasado un tiempo desde que disfruté de las paredes de azulejos en climas cálidos...

I don’t know—next time someone asks me an obviously tendentious question about what I think of #DEI , I’m going to go, “Hey, I didn’t go to #Caltech , so I steer clear of these house rivalries. But I do think House #Corrino has a good fighting chance against Slytherin House in the #finalfour. How’s about you?”

End of Mission

One year ago on this day, Perseverance lost her little flying companion Ingenuity to the dunes of Valinor Hills.

When I was a baby, my parents lived near #Caltech (for dad's chemistry postdoc) and #Pasadena City College, in a neighborhood so far spared from the current #wildfires, in a house built in 1916; their rent at the time was $125/month.

After we moved to NYC, my mom used to tell me longingly about the fruit trees -- apricot, orange, and grapefruit --overhanging our house. The grapefruit tree occasionally dropped hefty fruit on our bedroom roof, which would wake her (and me) up at night. "Truly it was paradise. I never wanted to leave California."

Mysterious Submerged ‘Lost World’ Discovered Beneath the Pacific Ocean Stumps Scientists

An international team of geophysicists using a new imaging technique that measures the speed of seismic waves caused by earthquakes to locate the juncture of tectonic plates in the Earth’s mantle say they have discovered the remnants of what appears to be a “lost world” beneath the Pacific Ocean.

Previous methods to locate these junctures between tectonic plates have always found them where scientists expected them to be. However, this latest joint effort by geophysicists from ETH Zurich and the California Institute of Technology (Cal Tech) found indications of these zones at locations that display no indications of tectonic plates or other recent tectonic activity.

According to a statement from the researchers, these findings have left them asking, “Is there a lost world beneath the Pacific Ocean?”

#Caltech has set up an employee relief fund for the #NASA #JPL employees who have lost homes in the #EatonFire in #Altadena. There are many who have lost everything, among them my friends and former co-workers. Read about it at the link. Please consider donating. 100% of your donation is US tax deductible.

The Fires of Los Angeles

The wildfires that broke out on 7th January in various parts of Los Angeles have now been raging for three days and, initially driven by very high winds, have destroyed thousands of properties. Almost 200,000 people have been forced to evacuate their homes but so far it seems the loss of life has been limited. Let’s hope it stays that way, though realistically the death toll will probably rise.

The fire that broke out in the Eaton Canyon is still burning over a large area to the North-East of Los Angeles near Pasadena, which is the location of the California Institute of Technology (Caltech), NASA’s Jet Propulsion Laboratory (JPL) and the Carnegie Observatories. Through astrophysics and cosmology I know quite a few people working at these establishments, including members of the Euclid Consortium. As far as I know neither place has been directly affected by the fires, though they have been closed due to heavy smoke and wind damage. I found out today, however, that some colleagues working there and living nearby have lost their homes and all their possessions to the flames. At least they themselves – and their families – are safe and accounted for but it must be a very grim time for them.

When the smoke has cleared I hope they will get practical assistance needed to start that process. In that vein, I see that a Caltech and JPL Disaster Relief Fund has been set up. You might consider making a donation.

On a more personal note I have an old and dear friend – not an academic – who lives near Santa Monica in the area marked on the map as Palisades Fire. Looking at the satellite pictures it seems his home has been destroyed too. It was, however, placed under an evacuation order some time ago. I assume he complied and is safe and sound, though I have so far been unable to contact him.

My thoughts are with anyone affected by these terrible events.
