There's so many people paranoid about the remote possibility of dirty bombs. Meanwhile, Norfolk Southern is actually spilling tankers full of toxic chemicals that get set on fire by being incredibly negligent.

If terrorists did want to poison an area, there's plenty of insanely toxic and commercially available compounds to choose from. The fixation on nuclear fuel is an indicator of someone who is just repeating a ghost story and doesn't actually know/care what the biggest sources of danger are.

So a salad served with croutons is a sandwhich?

Printing off a photo at a photo center is already highly automated and trvially easy. So yeah, I agree that the people comissioning portraits don't care if there's a cheaper and easier option. These people are making an emotional purchase and don't have to worry about some trifling thing like a budget.

Harvard is a $50 Billion endowment fund that happens to run a school. So Harvard divesting from Israel affiliated investments is potentially significant.

I believe that's usually expressed as mutiples of your annual income with the general idea being that if you hit those benchmarks you should be able to maintain your current quality of life in retirement. So if you make 50k euro, Fidelity would want you to have 50k total savings by age 30, 150k by age 40, 300k by age 50, etc. People in the US generally plan on a 4% safe withdrawal rate. So the 10x savings that the Fidelity chart recommends at retirement age would provide a safe 40% of your prior income withdrawal with social security making up the rest.

I personally express my own savings goals in terms of desired retirement income since earned income can vary quite a bit. In which case if I wasn't counting on social security I would want to have 1/(4%) = 25 x my annual retirement income before retiring. 25x is definitely a big mltiplier, but if your actual spending level is significantly lower than your current income level, it's a lot more attainable than it initially sounds.

I mostly like how this article frames time to retire based on savings percentages. It's worth a read. https://www.mrmoneymustache.com/2012/01/13/the-shockingly-simple-math-behind-early-retirement/

If an upvote is an "I like this" button, then it's bad UX design to expect people to not use the downvote as an "I don't like this button." If there needs to be an "off topic" button then it shouldn't be styled and placed to look like the exact opposite of the "I like this" button.

Frozen food is processed way closer to where it's grown as opposed to the produce that might be shipped across hemispheres before you get it. So frozen stuff tends to be more consistent in quality.

Tech Jesus is a colloqial name for Steve Burk of Gamers Nexus because of his hairstyle resembling old depictions of Jesus.

My parents are around 44 deg lat and their tomatoes do very well. It seems like something else must be limiting your success.

I won't actually recommend doing so, but I've definitely contemplated sending glitter bombs to prior landlords who made up charges to withhold security deposits.

I could be wrong, but I think XRD requires very pure crystals of sufficiently large size. That can help you ascertain the structure and composition of something you can synthesize and crystalize, but I don't believe xrd can image specific regions of interest like single doping sites like this article talks about.

Synchrotron XRD also has a major drawback in having a very significant equipment requirement that requires being able send samples away for analysis at a dedicated facility. That puts limits on sample preparation and stability time, as well as sharing beam time with lots of other groups.

It's been a while since I've read up on synchrotron xray diffraction though, so there could be workarounds for some of those limitation or I could be misremembering details.

These images are generated from processing many out of focus images while scanning across the area. They use the differences between the out of focus images to compute what must have caused those differences.

So this technique is pretty far from being able to capture real time events as it requires capturing hundreds of images to produce a single computed image. The paper talks about how thermal motion of the nuclei is what now dominates the limits of resolution for this method.

There are other ultrafast imaging techniques that can capture essentially real-time chemical reactions, but I believe those don't come close to this spatial resolution.
