Typical physicist, ignoring enthalpy of phase changes. Starting from 1C defrosted makes a huge difference from 0C as the melting takes up a ton more energy/slaps. Their underslapped chicken would give you salmonella

science@lemmy.world•Scientists create the world's thinnest spaghettiEnglish
23·2 years agoIt’s literally in the paper! "The nomenclature varies with the diameter of the fibers (and region), including ∼2 mm spaghetti (small string), ∼1.75 mm vermicellini (little worms), and ∼900 μm capellini (little hairs). The narrowest diameter mass-produced pasta is ∼800 μm capelli d’angello (angel hair), although thinner pasta lunga is produced by hand exclusively in the town of Nuoro, Sardinia: su filindeu (threads of God), which is estimated to have half the diameter of capelli d’angello and is, to the authors’ knowledge, the thinnest pasta created by hand to date "
The same people who presumably fill balloons with helum, want to cut down on sodum in their diet, prevent Iran from refining uranum, power their phones with lithum batteries, and enjoy singing David Guetta’s house classic Titanum

Ask Lemmy@lemmy.world•Vegans of Lemmy, would you eat lab-grown meat?
9·2 years agoThe energy for lab grown meat has to come from somewhere - thermodynamics is always king. You can provide it via sugars/carbohydrates which the cells can motabolise, but you’ve got to put energy into making the sugar/carbs which is easiest by just growing some sugarcane/potatoes/etc. There’s more steps for meat vs plant and it’s very unlikely you can make 100 calories of lab meat with lower total system energy input than 100 calories of plant matter. (N.B., I’m a chemist, not a astronomical biologist, so if an expert refutes me and my assumptions, Place more trust in them)

Technology@lemmy.world•Longi claims world record-breaking 34.6% efficiency for perovskite-silicon tandem solar cellEnglish
9·2 years agoI dont know this work, but have had a hand in some solar cell research (nanomaterials development), so can give a little context. This is a “one off” in so much as it will be centimeters sized lab based sample, although it has been repearedto verify. The current cost difference is astronomical versus mainstream (silicon) panels, but that’s typical of new discoveries. To be more exact, this is TRL 4 (technology readiness level 4) which is a scale that goes up to 9. Things only start getting cheap as you get towards the top. As for what the expected price of these materials would be, we don’t usually know for sure, although as this is a tandem cell it must be more expensive than mainstream as it literally builds a perovskite cell on top of a silicon one. They will never be used for mainstream - this is a specialist material.
The perovskite itself might make it as a general use solar cell. They have good efficiencies and you don’t have to make pure silicon (which is a bitch) and can in theory make them cheap and easy. As for time frame, I’m a bit of a skeptic it will ever be really used as there are a couple of issues this tech needs to address before it’s viable (#1, they degrade in air and encapsulating them adds new issues) and we already build silicon factories so that is soooo cheap versus building new factories to make long-term-cheaper cells. Factories are expensive. But in theory, anyone could push it to the mainstream within a decade.

Reddit@lemmy.world•It's time to admit Lemmy has won the "the biggest reddit alternative" award, why it's time for all of us to consider supporting it (here's why) + reopening r/LemmyMigration
14·2 years agoCan’t believe how many people went through the same steps. I miss reddit, but post RIF, it was unusable

Asklemmy@lemmy.ml•You are diagnosed with cancer but have no money for treatment. You've no option but to steal the money somehow. What's your plan?
6·3 years agoThe money is a means to an end. It would be more efficient to steal the drugs themselves. As a first guess, threaten a doctor to steal the drugs and write out a detailed rota of what to take and when for you. Depending on the means used to coerce, leave the country afterwards. Or just live in a country with socialised healthcare

Ask Lemmy@lemmy.world•What is one show you wish wouldn't have gotten cancelled when it did?
11·3 years agoSarah Connor Chronicals. Was pretty good throughout but then ramped up to off the walls amazing, just in time to be cancelled on a cliffhanger

1·3 years agoIf you delete comments, they still exist (but are hidden from the public) so reddit can still sell the content/conversation to 3rd parties, eg for training language models. If you edit the comments first, it makes the conversation nonsensical and reddits “product” is less valuable

Fediverse@lemmy.world•With all this talk about sync's pricing...English
209·3 years agoIt’s also possible to use the free version and just deal with ads. If you want lemmy to thrive, then sync is exactly the sort of thing we need (it’s the only reason I’m here after the final death of RIF)


The conversion from protons to neutrons does not complete 100% so there are still some (trillion) protons left per “atom”
