I love illusions. Just came across this one tonight. Believe it or not, the shadow is produced by the box (not the bunny). We talk about artifacts all the time but I often wonder how illusions manifest in medical imaging. Here’s a fun @RSNA paper about it pubs.rsna.org/doi/pdf/10.114…

Do not normalize Donald Trump. Yes, he won 2nite going away. But Donald Trump refused to participate in the peaceful transfer of power, he tried to overthrow an election, he committed crimes attacking our democracy, & he’s pledged to be a dictator. Do not normalize Donald Trump.

@yuanjamesrao It really depends on the probability of nuclear spallation events. It might go through at low LET, but very different story if it collides with another nucleus

@MichaelOumano I guess if it all got absorbed within 1L, then 30gy single fraction is somewhere between clinical injury and bodily obliteration! Stopping power of body tissue is probably negligible to EeV & it probably has a bragg peak deep in the ground, if not on the other side of the earth.

The Amaterasu particle was an extremely high energy cosmic ray (240 exa-eV). It had the equivalent energy of a brick dropped from waist level, except in a single particle (likely nucleus C or O). If this particle had impacted a person, what would be the #radonc biological effect?

@yuanjamesrao Love this question.Well there’d likely be a ton of spallation events w v high E+LET scatter going far in all dirctions.2.4x10^20eV=38.5J so IF this were unifrmly deposted in 1 L of water, that’d be 38.5 Gy…pretty sure we don’t even have σ data for Es that high for a reliable sim

My intuition is that nothing happens. If infinite LET and killed every cell along a line, the body would be unharmed and wouldn't be a detectable injury. However if it impacted another nucleus, and those chain reacted and now 1% of body atoms now moving at relativistic speeds...

@HikesWithDogs00 I forget which of our two dogs is the caterpillar 🤣

@MichaelOumano What's your caterpillar's name?

Love my #FathersDay present this year (super comfortable material too)

@DrMarinaSala Just bought it!

During my spare time this year, I decided to put a little KIDS book together. If you have little girls, you can order on AMAZON here. More books to come :) #kidsbook a.co/d/2AXCqPE

@historyinmemes Crazy that there were such significant outbreaks of the plague in England over such a long period of time (14th through 17th centuries). They didn’t understand the source until the late 19th.

In the year 1665, a significant number of deaths occurred in London, and a historical document known as the 'Bill of Mortality' provides information regarding the causes of these deaths and the corresponding casualties. The document specifically focuses on the period between August 15th and 22nd, 1665. During this period, numerous individuals lost their lives due to various causes in London. The 'Bill of Mortality' serves as a valuable record of these deaths, shedding light on the circumstances surrounding them. It is important to study and understand this document to gain insights into the mortality patterns of that time. The 'Bill of Mortality' recorded and categorized the causes of death, providing a comprehensive overview of the prevalent ailments and conditions that led to fatalities during that specific period. By analyzing this document, researchers can gain a deeper understanding of the health challenges faced by Londoners in 1665 and the impact of those challenges on the population. Studying the causes of death in historical contexts like this offers valuable information for researchers and historians, enabling them to assess the health and well-being of communities in the past. Furthermore, it helps us appreciate the progress made in medicine, public health, and disease prevention over the centuries. By examining the 'Bill of Mortality' from August 15th-22nd, 1665, we can gain insights into the specific causes of death during that period in London and better understand the health conditions and challenges faced by the population at the time.

Played around with the Cancer Imaging Archive today and I’m very impressed. I’m hoping I’ll soon have access to the Low Dose CT Image and Projection Dataset (had to specially request for some reason). Big kudos to all who’ve made this freely available

@ThePhysicsMemes Why no integral name that corresponds to “pop”? Absackle goes w crackle and absock goes w lock but no integral seems to go w pop

Ask some astrophysicists, they will find some super mega name for it. #datascience #teacher

Sea surface temperature (SST) craziness has returned to the North Atlantic. Covering daily data for 44 years (15,119 days), the North Atlantic SST anomaly just equaled the previous record level set on May 14th at 0.891°C above the 1982-2023 mean. Data: climatereanalyzer.org/clim/sst_daily…

With due respect @emilymbender I really think you are thinking about this the wrong way. 👉 Congress won’t help any of us if we can’t find common ground 👉 There actually *is* common ground, since all of us are actually concerned about systems that are unreliable, poorly controlled and overly empowered 👉 The media has rightly started to ridicule the internal squabbles 👉 In the end, these squabbles are only empowering big tech to do exactly the things you don’t want it to do

@unusual_whales fine is way too low

30,000 Amazon employees were able to listen to Alexa customers’ recordings between the period covering August 2018 and September 2019, per the FTC. Amazon has paid $25 million to settle the allegations.

Scientists have taken the world's first X-ray signal (or signature) of just one atom. This groundbreaking achievement could revolutionize the way scientists detect the materials [read more: buff.ly/42hbW3B]

4yo used the word “indivisible” perfectly (unprompted) in normal dinner conversation tonight

@HikesWithDogs00 Very true. I knew it wouldn’t be easy. Gave it my best shot.

@MichaelOumano In the famous words of Walter Grant, my first boss, "Everything you don't know how to do looks easy" (not saying you don't know how, but thought it was apropos! :))

I have no words. The world's oceans are 0.4°F warmer right now than any other year on this date on record. A single year... sitting 0.4°F above the previous daily record. How do we even tell the public this?

@HikesWithDogs00 Such a rough game! Some people make it look so easy though. Thought I’d give it a try

@MichaelOumano Extending my sympathy, it's a rough game.

Appearances of a contrast swallow. What’s the diagnosis?

Huge fan of this idea

@GaryMarcus @vkhosla @OpenAI 🎯

Five replies to an excellent question from @vkhosla, an investor in @openAI, about why we might seek more transparency from OpenAI or Microsoft than Coca Cola. 👉 The difference in the exact formula between Coke and Pepsi is likely to have little impact on public well-being; the exact formulation of AI systems could have significant impact. Even if the exact algorithm might were kept proprietary, the data selection is likely to have significant impact on people’s behavior and political choices. 👉Even people who do not opt in to using LLMs will likely be affected by them; I don’t drink Coke but it doesn’t affect me much if you do. LLMs might well affect eg the political leadership of non users. 👉 OpenAI has suggested that there are dozen major risks but left it to society to mitigate those risks and bear those negative externalities: greater transparency could be useful to mitigate those harms: exact details of Coke are unlikely to greatly affect public health measures etc 👉 Coke has not branded itself a “Responsible Soft Drink Company” or “OpenSoda” nor issued a grand corporate proclamation promising transparency. 👉 Coke is not a nonprofit; OpenAI is.

Why don't you ask Coke to disclose it's formula?
