The shingles vaccine is incredible #learnsomethingnew #sciencefacts #vaccineswork TikTok video by Alex Falcone

This video is imparting genuinely amazing news about the shingles vaccine, but also contains a description of vaccines that made me laugh so hard I had to sit down. β€œWe inject the dead version so that when the live one shows up it knows we’ve killed before” is both accurate and SO FUCKING FUNNY

there is never a good time or place, said this critic. too much to do, not enough resources or time to do it.
but yeah, im with you. how we gather feedback and id problems or solutions or concepts of a solution is never easy. definitely a multisolving candidate though;

They built a system specifically for precision, so i agree. The irony is that, from a cost loss perspective the road to improving is higher pod first then tails into lower false alarms.

I think the social penalty is incurred only if there is no explanation. the social contract has to be renewed and renegotiated with our constituencies. warnings are a service not just a text product

Evidence to warn is overrated. Lead time is about taking chances and yes β€œover” warning. Imperfect observations, imperfect science …

Not sure we have a system for the tyrrany of the tiny or single storm, let alone design a precise one. But i think we can have a more robust approach.

Loud frog. Not a peeper, though the volume was still high from nearby peepers; this green fellow was calling out vigorously

Lunchercise brought me to these loud fellows. Two kingfishers, two pileated (same ones) and a host of small birbs were all very excited to be in nice wx.

Study Finds That Execs Are Outsourcing Their Thinking to AI The same class of business executives who heaped AI onto us by the shovelfull aren't immune to its effects.

An LLM does not need to pull a trigger or automate a missile to serve the cause of war. It can work to make obscene violence feel justified and rational β€” to give you the illusion that you have β€œthought the matter through.” 🧡

Design agency price list displayed on black letterboard: ranging from 'WE DESIGN EVERYTHING' at 500 EUR to 'YOU DESIGN EVERYTHING' at 8000 EUR, with prices increasing based on client involvement. Shows ironic pricing structure where less designer involvement costs more.

Being close is all we should expect. Precision isnt the goal, just beyond our capability. and definitely a value add for estimating the worst case scenario

The book will teach you little unless you put organized effort into reading it, for active, directed work is necessary if you wish to understand and remember what you read. Careful, intelligent reading of this book will mean that you understand better what you learn in class.

What many students do not realize, however, is that we can relearn what we have once learned, providing we have learned it well in the first place. Thus, this book provides a convenient auxiliary memory that can serve you all of your life.

BOOKMARK 
How to Get the Most Out of a Book 

1. Skim through the assigned reading so that you will know what it is you are to study. 

2. Read the text carefully. Do not forget that many important ideas are presented in graphs, diagrams or maps. 

3. As you read, stop now and then and recite to yourself, in your own words, the important ideas in what you have just read. 

4. Make brief notes in the margin. These will serve as cues for subsequent self-recitation. 

5. Mark important or key passages for later review. 

6. Review the material at least once between the first time you study the assignment and study for exams. Make use of your marginal notes as cues for self-recitation. 

7. Remember that a little relearning is necessary each time you wish to use what you have learned for an examination, a related course, or for independent study. If you use the author's headings, marked passages, and brief notes for cues it will help you relearn easily. 

8. Coordinate what you read with what you learn in the classroom. Keep well-organized lecture notes. Lecture notes that are legible and accurate will, like your text-book, serve in the years to come as quick and inexpensive keys to the knowledge that you are acquiring.

Yesterday, I was reading a used book from 1959 I bought some years ago, and I found this bookmark, which must have been there when I bought the book.

Given the age of the book and Deese at Johns Hopkins, the bookmark would be from the 1960s. Useful advice to students even now.

Hannah Ritchie has built a fun little tool where you can compare energy usage of various products and activities.

This is super helpful imho, because it's so hard to develop intuitions even just about the scales involved here.
