I meditated today with Rider - Temperance XIV , and Thoth - Art XIV. Initially I was a bit surprised by how dark the meditation went with Temperance. This angel told me I needed a heart, and to deliver a cruel message to someone I know. The liquid that Temperance was mixing appeared green, stall and old. I asked why the communication was so bleak. The angel explained it was because I was fearful. ••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••• Interestingly enough, my mediation with Art was incredibly different. I immediately imagined myself as this being. Light and dark did not matter. There was no rush of energy one way or the other. Both sides were present and both were accepted. This card was comfortable, content and relaxed. The chemist was mixing and creating what was needed to restore balance along the companionship of a few animal helpers. ••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••• The differences in these connections are an easy way for me to identify which deck is my primary. Moreover, I recently thought about how much I enjoy the Rider imaginary and the Thoth substance. Low and behold, I discovered a deck today that claims to have this exact mix. We will see how this resonates. ••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••• #healing#transmutation#chemistry#alchemy#riderwaitesmith#thoth#shadowwork#aleistercrowley#pamelacolemansmith#nashvillemom#nashville
Fluorite, or fluorspar, is a mineral of calcium fluoride, CaF2. Depending on impurities crystals often have characteristic colours or show fluorescence (to which the mineral lent its name). Fluorite lenses are used in microscopes and telescopes because of their low level of chromatic dispersion. Treating CaF2 with sulfuric acid yields hydrogen fluoride, HF. It is used to make fluorine compounds like teflon, a non-sticking, heat resistant coating for frying pans, and cryolite, Na3AlF6, from which aluminium metal is made.
Fluorite crystals are often found in the shape of cubes or octahedrons. The crystal structure can be described as a cubic close-packing of calcium ions in which fluoride ions occupy all tetrahedral holes, or alternatively (because F- ions are in fact larger than Ca2+ ions) as a simple cubic packing of fluoride ions in which calcium ions occupy half of the cubic holes. The arrangement has a cubic face-centred cell and adopts spacegroup symmetry Fm-3m.

First real failure with slide film on this roll. My previous two sheets of 5x4 were a little dark but I put it down to my error with exposure. That wasn't the case, turns out my chemistry was tired. First developer shot along with Blix. Managed to salvage something with a re-run using fresh Blix but lesson learned. Never had C41 chemistry go off quickly so didn't expect E6 to be any different. #chemistry#fujiprovia100#slidefilm#portrait#hasselblad500cm#colourshift#failure

🚗ASPHALT🚙 Asphalt, also known as bitumen, is a sticky, black, and highly viscous fraction of crude oil.
Fractional distillation is used to separate crude oil into simpler, more useful mixtures. This method can be used because different hydrocarbons have different boiling points.
Long hydrocarbon molecules have stronger intermolecular forces, so they have high boiling points. They leave the column as hot liquid bitumen.

You know what this is? Pure beautiful natural rose absolute from one of the best producers. It's at 100% strength. Diluted in alcohol it's great, and perfumers use it carefully, within the strict regulations, so it's safe.
So when I see someone saying that they only use rose absolute on skin because it's natural, but that they won't use "chemicals " I despair.
Roses are made of chemicals. Humans are made of chemicals. Read the contents lists. Nature uses chemicals to make roses! Just off to bang my head on the wall. Back soon.

So I was offered a promotion at my job that may cause me to take a few steps back from the science end of my field. And as I sit here considering the position I feel a slight disconnection from 2 different sides of me, the art and the biology. Which is funny bc I've been wanting to find a way to merge the two for a while now, but hey maybe what I need is a step back in order to do just that. So heres a lil journal page filled with notes and drawings about birds, moss, and lichen from a conference I went to a while back to represent that idea.
Sorry for the long text feel free to not read~
Failed Chemistry 🧪
It’s been one of those weeks where a lot of experiments haven’t worked. Your reaction turning into black gunk isn’t always a bad sign but this week it was. Cleaning up for the week this afternoon was FUN.
I will still be able to talk about these experiments in my thesis though. In the main body of a chemistry thesis you’re expected to unpack the “story” of your research i.e. what experiments you tried until you managed to make your desired molecule.
Time to try again next week. I’m so close to finishing off some less successful sections of my project. I just need to make a few more compounds then I can focus on the molecules that are working the best.
Anyway, now it’s time for the weekend. If anyone is planning to be in London tomorrow - be it to march against Brexit or not - I’m going to be at the @sciencemuseum on the 2nd floor leading a drug design activity as part of their Chemistry Festival. See you there?
How has your week gone? Productive? Unproductive? Let me know in the comments below.
Last month, as an extra credit assignment I watched a documentary about Percy Julian, a research chemist and a pioneer in the chemical synthesis of medicinal drugs from plants. He was the first to synthesize the natural product physostigmine, plus a pioneer in the industrial large-scale chemical synthesis of the human hormones progesterone and testosterone from plant sterols such as stigmasterol and sitosterol. His work laid the foundation for the steroid drug industry's production of cortisone, other corticosteroids, and birth control pills.
I told my classmate that I made my father, mother and aunt watch it and he laughed and said “you would torture them like tht?” To which I replied... “he’s the first black chemist I’ve ever seen before... growing up... I didn’t even have black teachers.” He got quiet for a second and shook his head.
My god baby will see black doctors, will know success, coming from a family full of successful men and women. Her own mother paving her way. I didn’t understand these things as a child, but ohh how the Lord has opened my eyes. I love you Dr. Winnie, superhero Winnie, teacher Winnie. Whatever u decide to be. We got ur back 🥰🥰👩🏽⚕️👩🏽🌾👩🏽💻👩🏽🏫👩🏽🎨👩🏽⚖️👰🏽👩🏽🚀 ・・・

Гамма-излучение / Gamma-radiation ⚛️
Самая опасная для человека особенность ионизирующих излучений- это их невидимость. Для того что бы "почувствовать" радиацию, ученные уже давно придумали дозиметры, приборы измеряющие плотность потока излучения и вычисляющие дозу радиации, которую может получить человек при контакте с источником.
На видео- контрольный источник гамма-излучения (γ) для калибровки дозиметров и спектрометров.
γ-излучение имеет наибольшую проникающую способность, радиационный детектор "видит" за несколько метров даже этот слабый калибровочный источник. Бояться радиации не надо, но работать с ней нужно очень осторожно 👨🏼🔬
The most dangerous feature of ionizing radiation for humans is their invisibility. In order to "feel" the radiation, scientists have invented dosimeters, instruments measuring radiation flux density and calculating the dose of radiation that a person can receive when in contact with a radiation source.
This video shows gamma radiation (γ) source, used for calibration of dosimeters and γ-spectrometers.
Among other types of ionizing radiation, γ-radiation has the greatest penetration ability, as you can see, radiation detector easily picks up even this weak calibration source from a few meters distance. You do not need to be afraid of radiation, but you should be careful, while working with it 👨🏼🔬
UN lauds special chemistry of the periodic table, kicking off 150th anniversary celebrations
On Tuesday, the United Nations Educational, Scientific and Cultural Organization (UNESCO) launched the International Year of the Periodic Table of Chemical Elements at its headquarters in Paris, kicking off a series of events and activities to be held throughout the year, as the world celebrates the 150th anniversary since its creation by Russian scientist Dmitri Mendeleev.
The decision two years ago by the UN General Assembly to hold this year-long celebration aims to recognize the importance of the periodic table as “one of the most important and influential achievements in modern science, reflecting the essence not only of chemistry, but also of physics, biology and other basic sciences disciplines”. The launch event held in Paris brought together scientists and representatives of the private sector, and was opened by UNESCO’s Director-General, Audrey Azoulay, featuring notable guests such as Mikhail Kotyukov, Russia’s Minister of Science and Higher Education, Pierre Corvol, the President of the French Académie des Sciences, and Professor Ben Feringa, 2016 Nobel Laureate in Chemistry.
UNESCO will present its educational initiative, 1001 Inventions: Journeys from Alchemy to Chemistry, designed to help young people in schools all over the world improve their understanding of chemistry and its numerous uses. . .
