Wait a lot of medival paintings are actual enciphered forms of storing information?

Like chemical formulas to avoid others copying their processes.

I think that may be cool as shit to look into more some day.

(Also some reactions only work because of impurities in the local source of the material, which makes it even harder to figure out and reproduce today)

A covalent bond is a chemical bond that involves the sharing of electrons to form electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs. The stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.[1] For many molecules, the sharing of electrons allows each atom to attain the equivalent of a full valence shell, corresponding to a stable electronic configuration. In organic chemistry, covalent bonding is much more common than ionic bonding, where atoms are separate and merely associated by electrostatic attraction.

While saddened to hear of the passing of John Walters:
https://www.northfieldfuneral.com/obituaries/John-Philip-Walters?obId=49304173

I delight in the memory of his Analytical #Chemistry and Instrumental Analysis courses at #StOlaf College in #Northfield Minn. These had amazing labs using Commodore 64s that had build-in serial comm, GPIOs, and ADCs that could all be programmed in BASIC. We could create our own instruments!

He also would write up notes and photocopy them for the class at home in the middle of the night (in 1983!).

💁🏻‍♀️ TIL: ⚡💧 Researchers at the #MaxPlanck Institute found that #rain can corrode surfaces through an overlooked electrical mechanism.

When drops slide across insulating #materials, they pick up charge through slide electrification. Those charged drops can then breach protective coatings through dielectric breakdown, exposing #metal beneath to corrosion.

Hey, can I get a #chemist on the line? Maybe one with #cosmetic or #polymer knowledge?

So, I have psoriatic arthritis, and a manifestation is a degradation of my nails. And I was looking into a product, which is advertised as "beneficial" to one's nails, which is not a thing associated with manicure products.

It is a #uv cured gel, but rubberized in some way.

Here's the thing, all of these "gel" or uv cured products appear to be #resin.

Am I wrong in assuming that both long term exposure to resin and UV is incredibly dangerous? When I've done resin work, I've been fully masked and gloved and all of the safety sheets say to avoid skin contact. I stopped working with it because of safety and environmental concerns.

How is nail resin any more safe?

रासायनिक मूलद्रव्यांचा शोध – दमी. त्रीफोनोव, व. त्रीफोनोव (Chemical Elements How They Were Discovered In Marathi by D. N. Trifonov, V. D. Trifonov )

या पुस्तकामध्ये आपण रसायनशास्त्रातील “मुळाक्षरां “ची कशी रचना झाली, तसेच आपल्या चौकस बुद्धिमत्तेतून संशोधकांनी एकामागोमाग एकेका नव्या मूलद्रव्याचा शोध कसा लावला याचे विवेचन करणार आहोत.

बहुतेक सर्व रासायनिक मूलद्रव्यांवर अनेक पुस्तके लिहिली गेली आहेत. त्यांची संख्या एवढी प्रचंड आहे की त्यांचे एक स्वतंत्र ग्रंथालयच होईल. त्या पुस्तकांमध्ये, मूलद्रव्यांचा अंतर्भाव असणारे खडक व खनिजे, त्यांच्या नि- एकर्षणाच्या विविध पद्धती, मूलद्रव्यांचे भौतिक आणि रासायनिक गुणधर्म यांचा आढावा घेतलेला असतो. काही मूलद्रव्ये आश्चर्य वाटण्याएवढी मुबलक आहेत. त्यांचे उपयोगही अनपेक्षित वाटावेत एवढ्या भिन्नभिन्न क्षेत्रात केलेले आढळतील. खरे तर आजच्या प्रगत वैज्ञानिक युगात प्रत्येक मूलद्रव्याचा काहीना काहीतरी महत्त्वपूर्ण उपयोग आहेच आहे असेच दिसेल. प्रत्येक मूलद्रव्याचे त्याचे स्वतःचे असे खास “चरित्र” असून ती सारी आपापल्या परीने वैशिष्ट्यपूर्णही आहेत हे खरे की मूलद्रव्यांच्या शोधांच्या इतिहासाबाबत अद्यापीही बरीच संदिग्धता आहे व इतिहासकारांना न सुटलेले प्रश्न अजूनही सोडविता आलेले नाहीत. कुणी सांगावे, त्यांच्यापैकी एखादा- दुसरा इतिहासकार तुम्हीही असू शकाल !

💁🏻‍♀️ TIL: 🎲🧪 A collective of game designers called The Mint Tin Guys created a 120-sided #aluminum die for #DnD that features all 118 known #elements from the #PeriodicTable engraved on its faces. The remaining two sides are "wildcards."

Very excited that we will be hosting Madelon Maurice for a @LED3hub Lecture on June 25th. I am looking forward to learning about their work on new degrader modalities and the Wnt pathway.
