this is how 238Pu ceramic pellets for space probe generators look like, no fission required just alpha decay. If it was fission, it wouldn’t need to glow like this entire time because you can just turn it off

i don’t mean beta-oxidation, it’s just a series of separated normal reactions. i mean something like this: when first learning about ketones, you might learn about aldol condensation, which has enol as a nucleophile and another carbonyl as electrophile. at some other point you might learn about strecker reaction, which has iminium ion as electrophile and cyanide as nucleophile. but really, what you can do is mix and match, and you can pair enolizable ketone and iminium (mannich reaction) or carbonyl and cyanide (cyanohydrin formation) and then generalize, for example you don’t need strictly ketone for mannich, you can use any electron rich conjugated system like malonate or nitroalkane anion (henry reaction) or phenol or indole. to figure this out you need to study mechanisms. these last two are usually treated as variants of friedel-crafts reaction, but really categories like this are fake

and to get that right, you need to know how these reactive intermediates look like, how reactive they are, what influences their stability which means that ochem starts with discussion of carbocations, carboanions, radicals, their shapes and orbitals involved, hyperconjugation, solvent effects and the like. and then first reactions taught are sn1/sn2, because these showcase these fundamentals nicely, and from there, it’s about introduction of more compound classes

we only had synthons introduced during lecture at around 4th year, and only for ochem path, it’s not doing a lot at that point and imo would have much more impact right after ochem intro course

i always thought that the idea of synthons should be taught early on https://en.wikipedia.org/wiki/Synthon

i’d say it’s more important to learn mechanisms because this way you can notice these patterns of reactivity easier. at some point you’d only get new reactions that are really just pieces of other reactions you know put in a new way

there’s zero reason to make chart like this, it’s both barely comprehensible and touching surface level stuff only (where are palladium couplings for one)

These things are under high voltage, so no. And then there’s several kg of mercury inside

no, but they will also kill you (but not by magic)

i think that conspiracy theories are more about feeling special about knowing some secret knowledge, lots of people fall for this and even create conspiracy theories without realizing, no matter how smart they are

Aristotle said so much dumb shit, like he said that women have less teeth and never bothered to check

check again, works for me just as usual

it might be reddit just fucking up, i got the same error while logged in

i guess that fb does store keys after all; they do respond to police requests

i also found this: https://www.reddit.com/r/privacy/comments/v7tsou/is_whatsapp_lying_about_its_endtoend_encryption/

Encryption in WhatApp is actually a fake, because the encryption keys are generated and stored on Facebook’s servers, accordingly, they can read any of your messages as plain text, and the intelligence services obviously have access to them.

Also a few months ago there was a leaked slide from an FBI training course or something where they compared different messengers in terms of how well they cooperate with the police, guess who came first ?

WhatsApp provides data to the police in near real time (about 15 minutes from the time of the request)

The message from WhatApp at the beginning of the chat - that your data is not available to third parties is the height of hypocrisy.

whatsapp is not meaningfully e2ee

sounds like it’s not supposed to be a general use tool, but instead for counterintelligence only:

The Ministry of the Interior anticipates submitting around 30 requests per year for the surveillance of unencrypted messages and between 5 to 15 requests for encrypted communications. If there are 30 instances of encrypted message monitoring within a single calendar year, the Interior Minister is obligated to inform a permanent subcommittee of the National Council, which is the directly elected chamber of the Austrian Parliament.

Each surveillance method will require case-by-case approval from the Federal Administrative Court. The process involves a legal protection officer from the Ministry of the Interior, who will have three business days to respond to any request. Following that, a panel of three judges from the Federal Administrative Court will review the case. In urgent situations, an individual judge may grant approval, supported by a 24-hour judicial service system.

broad use would expose its existence and make any 0days useless in short order

firefox at minimum clears the very low bar of not exposing casual user to crypto
