Fun fact: fiestaware plates (this was the company that made the uraranium glazed ceramics) are commonly used by radiation safety folks as check sources and for teaching how to use survey meters. This is because they usually aren’t considered a radioisotope source, so there’s less paperwork to keep them around.
- Comment on Do rotating plates in microwaves help when heating food? 1 month ago:
As others have said, microwave ovens create standing waves with regions of higher power (hot spots), which unevenly heat food. If you want to see this for yourself, Scientific American has a kids project for measuring the hot spots in a microwave using chocolate or marshmallows. There’s also a bunch of videos on YouTube of people essentially doing this same project.
- Comment on Tenacious iPhone user finally unlocks phone locked for almost a decade 1 month ago:
Honestly this sounds like user error. From one of the links in the article:
As the journalist and Apple Store staff tested, if you insert the wrong passcode for 1 to 5 times, there will only be red notifications saying the passcode is wrong, and you needn’t wait to give it another try.
For the 6th time you insert a wrong passcode, it will report, “iPhone is disabled, try again in 1 minute”. And the phone will be locked, and you won’t be able to insert passcode again until 1 minute later.
For the 7th time, the iPhone will show, “iPhone is disabled, try again in 5 minutes”.
For the 8th time, the iPhone will be locked for 15 minutes, and for the 9th time, it will be locked for 60 minutes to insert passcode again.
If you insert the wrong passcode for 10th time, the iPhone will be disabled and you will have to connect it to iTunes to unlock.
Apparently if you jailbreak the iPhone the delays aren’t set correctly (or at least that was the case 10 years ago)?
On top of that, the user couldn’t just wipe the phone because they didn’t want to lose a video that wasn’t backed up anywhere else.

widely distributed them. Many of them went to civilians for legitimate purposes.
Source?
- Comment on Who still uses pagers? 2 months ago:
There are many sources because it’s been widely reported. Here’s one: reuters.

Seems unlikely considering only pagers belonging to Hezbollah had the explosives added.
- Comment on North Carolina is getting a $1.4B sodium-ion battery gigafactory 2 months ago:
The volumetric energy density is 60% of lithium ion batteries, but the energy density per kg is more like 75% since the batteries are lighter. Assuming that scales to the ev range, that’s probably sufficient for a lot of use cases.
- Comment on Smart sous vide cooker to start charging $2/month for 10-year-old companion app 2 months ago:
I have one of these. The sous vide cooker itself is very nice and easy to use, I’d highly recommend it. The app is a bit clunky and not necessary to use the device. I certainly wouldn’t pay $2 a month for it.
The app lets you set a temperature and cook time, but you can also do this using the buttons on the cooker. Sometimes the WiFi pairing is finicky, so honestly I skip the app half the time. The app also lets you view and write recipes. I guess the big advantage is you can click “start cooking” and it automatically sets the device temp and time, but doing it manually isn’t much harder. I’m also not wowed by the in-app recipe selection, and generally just get recipes from the internet.

- Comment on Google tests out Gemini AI-created video presentations 4 months ago:
That’s too straightforward - this is google after all.
There’ll be a new product that integrates this feature and they’ll call it Google Slides, while rebranding the old “Slides” as Google Presentations. Then in a few years they’ll kill off the new Google Slides, leaving only Google Presentations and tons of confused users.

When will scientists just self-publish?
It’s commonplace in my field (nuclear physics) to share the preprint version of your article, typically on arxiv.org. You can update the article as you respond to peer reviewers too. The only difference between this and the paywalls publisher version is that version will have additional formatting edits by the journal.
If you search for articles on google scholar, it groups the preprint and published versions together so it’s easy to find the non-paywalled copy. The standard journals I publish in even sort of encourage this; you can submit the latex documents and figures by just putting the url to an arxiv manuscript.
The US Department of Energy now requires any research they fund be made publicly available. So any article I publish is also automatically posted to osti.gov 1 year after its initial publication. This version is also grouped into the google scholar search results.
It’s an imperfect system, but it’s getting much better than it was even just a decade ago.

Source is Department of Mind-Blowing Theories by Tom Gauld. I skimmed through some other comics from the book and it’s a goldmine of content for this community. It’s also absolutely something my SO and I would enjoy, so I ordered a copy.
Thanks for sharing!

I am not reading your comment, I am simply traveling through it with my eyeballs. Also your comment doesn’t have gold fringe and therefore lacks jurisdiction.

I’m guessing they signed up for HP Instant Ink, a monthly subscription service that monitors the ink levels in the printer and automatically mails you refills.
If you buy an HP printer, they HEAVILY promote this and offer discounts/free trials. I declined, because fuck that, but I could see someone agreeing and forgetting about it.

- Comment on U.S. Govt and researchers seemingly discover new type of superconductivity in an exotic, crystal-like material — controllable variation breaks temperature records 10 months ago:
It’s already been published. But it’s superconducting at 10 K. This is a new high temperature record, but pretty far from room temperature.
- Comment on Scientists successfully replicate historic nuclear fusion breakthrough three times 11 months ago:
They’ve been doing studies of what would be required for ignition for a while, but have never demonstrated ignition using the Z machine.
If they did have ignition, there’s no way they would’ve let LLNL claim to be first and enjoy all the media attention.
- Comment on Scientists successfully replicate historic nuclear fusion breakthrough three times 11 months ago:
Nah, the Z machine never achieved ignition. That doesn’t mean it’s not a really cool facility though!
- Comment on Correlation, maybe causation? 11 months ago:
Interestingly, the journal editors have released an expression of concern earlier this year for this article and others by the same author.
SAGE Publishing has been made aware of scientific concerns regarding the work of Dr. Nicholas Guéguen. Multiple concerns have been raised regarding the integrity of the research including but not limited to concerns around data fidelity, replicability of findings, and ethical consent and oversight for studies involving human participants. SAGE Publishing’s Research Integrity Team, in cooperation with this journal’s editors, are currently conducting an investigation into these articles.
This expression of concern will remain in place until the investigation is completed and any further needs for appropriate action have been taken.
- Comment on ‘ChatGPT detector’ catches AI-generated papers with unprecedented accuracy 1 year ago:
The article is reporting on a published journal article. Surely that’s a good start?
- Comment on I'm a professional. 1 year ago:
I agree that anything generated by an LLM will need human verification for accuracy, but scientific abstracts are one of the few areas where LLMs can be immediately useful. I’ve played with having ChatGPT create abstracts in subjects that I’m familiar with and it’s been surprisingly good. It even respects word limits. If you have a block of text that needs to be condensed, ChatGPT can probably get you most of the way there.
For example, I had chatGPT summarize your comment in 5 words:
“Summarizing scientific articles demands precision.”
