In any theory for quantum black holes that allows information of in going material to emerge in the out going Hawking particles, the temperature is twice the value calculated by Hawking. How come no one seems to have noticed this before?

@NobelPrize Nobel Prize Physics 2022. Congratulations to Alain, John and Anton! Welcome to the Club ...

@CovidVaccinatie Wij zijn aan de beurt. Hoera. Maar wat een ondoordringbare jungle van “aanwijzingen”! Welk warhoofd heeft dat gedoe met die diviD bedacht? Handig en snel? Wij komen er na een paar uur klikken niet uit. Dan maar Corona.

Wat een ondoordringbare jungle van aanwijzingen. Zijn er mensen van boven de 60 die op het web een prikafspraak konden maken? “Handig en snel”? Welk warhoofd heeft dat gedoe met die divid bedacht? Ik kom er niet uit.

Eh ja, maar er hoeft maar een vlieg op te landen of je zit weer in de fabrieksinstelling: volume op de ene remote, kanalen op de andere

Heeft iemand een TV met glaskabel, die volledig kan worden bediend met slechts 1 afstandsbediening, waarvan alle knoppen goed functioneren?

@christianphagen @zguralnik @PhysRevLett @CERN @ATLASexperiment @CMSExperiment It’s about time that you read my 1970 paper: all massless unphysical particles cancel against each other

To all scientists who use LaTeX to make the slides for their Zoom presentation: please erase everywhere in your file your \pause commands. \pause does not work as intended, making your presentation difficult to follow
(without you noticing the bug)

@paulg I hope we can also agree on how to realise such objectives. Perhaps through the Russian people, helping them understand that they are being fed with mendacious propaganda, and that their government commits war crimes.

With NASA technology, it should be possible to develop remotely controlled robots, to be attached to cables, to save victims from a fall into a well or pipe such as what happened to little Rayan in Morocco.

To host extraterrestrial intelligent life, any planet will have to pass several necessary - while very improbable - bottlenecks.
I think it is unlikely that we'll ever detect intelligent signals. But nobody knows.

Congratulations to my friend and colleague Giorgio Parisi for the 2021 Nobel Prize in physics. Remembering frequent discussions in the 1970s about large N and other features of quantised field theories.

The rest of the world should decide to organise our measures to aid India, producing and delivering vaccines for 1.3 billion people, starting this minute. In addition we should think of Brazil and other countries where the situation is urgent. It’s also our own interest.

@AMAZlNGSCIENCE “if a black hole the size of a penny...”? That has a mass as big as earth itself, surrounded by a devastating gravitational field.

[Gerard 't Hooft @gthooft]

@hennybeck Yeah, I can do that kind of photoshop work too

[Gerard 't Hooft @gthooft]

Let me add my congratulations to Roger Penrose, Reinhard Genzel and Andrea Ghez, who share this year’s Nobel Prize in physics for their work on black holes!

My latest research indicates that the paradoxical features of quantum mechanics are caused by vacuum fluctuations.

@RPlasterk En kernenergie kan nog veel beter en veiliger, met nog minder afval. De grondstof blijft duizenden jaren volop beschikbaar.
Er is alleen nog wat meer onderzoek nodig. Waarom categorisch afwijzen?
