As we discussed it tomorrow at our #CustomerJourneyMapping workshop, scaling a business is a work of science 🗜️⚗️🔎🔬
Each product developer is an experimental scientist. Each scientist looks for evidences out there in the physical word to form a hypothesis that can explain a phenomenon.
Through exciting science projects and activities kids can easily do at home or school, tomorrow's scientists and engineers will have a blast learning about simple machines and how they make daily life easier. Young readers will also learn more about famous scientists and inventors!
‘The Kids' Book of Simple Machines: Cool Projects & Activities that Make Science Fun!’ by Kelly Doudna.
Look for this title on your NLB Mobile app! 📲📚
Unlike with ordinary matter fields, there is no such thing as the density of gravitational energy. The thing you would like to define as the energy associated with the curvature of spacetime is not uniquely defined at every point in space. So the best you can rigorously do is define the energy of the whole universe all at once, rather than talking about the energy of each separate piece. (You can sometimes talk approximately about the energy of different pieces, by imagining that they are isolated from the rest of the universe.) Even if you can define such a quantity, it’s much less useful than the notion of energy we have for matter fields. Saying “there’s energy in the gravitational field, but it’s negative, so it exactly cancels the energy you think is being gained in the matter fields” does not actually increase anyone’s understanding it just quiets them down. Whereas if you say “in general relativity spacetime can give energy to matter, or absorb it from matter, so that the total energy simply isn’t conserved,” they might be surprised but I think most people do actually gain some understanding thereby.
Energy isn’t conserved; it changes because spacetime does. See, that wasn’t so hard, was it?
The #research Gods smiled upon me today as I worked furiously to inquire (and dismantle oppressive, capitalist and patriarchal systems at the same time, can I get an amen?). Tomorrow I hope they will smile on me again as I continue my application.
After I finished today, I explored some of my new campus—be still, my heart—where I found the most glorious corner surrounded by tall windows that allowed the warmth of the sunlight to stream in. I sat there, laid down, and promptly took a mini nap. It was the best.
All while I was somewhere in the sky, blissfully napping, surrounded by the medical district.
Today this is what it looked like to be an #slp2b#researcher#scientist#txwomans#istudybrains#ialsolookatsystematicinequality#millennials
Today I spent most of my day teaching some year 12 human biology students! Todays class was all about PCR and gel electrophoresis, looking for a mutation in the BRAF gene in melanoma samples. I adore teaching and love being in the lab with excited and enthusiastic high school students. Tomorrow I get to do another class, this time about stem cells and cell culture.

Prof. Walter Lewin demonstrating an experiment to show the conservation of angular momentum.
When he folds his arms his moment of inertia decreases and angular velocity increases.
Angular momentum = moment of inertia × angular velocity (about any particular point)
Woohoo! My paper got accepted! It’s the final paper of my PhD! So grateful to my amazing supervisor for helping me make this happen! It explores how growth factors work synergistically to exacerbate cataract. Free download till Aug 7: authors.elsevier.com/a/1ZF0E3Imr1UBE Link in bio!

Women in crystallography 💎 .
Despite suggestions by some that women have long dominated the field of crystallography, the numbers would suggest otherwise.
The International Union of Crystallography's online list of eminent crystallographers is approximately is 90% male. .
The Ewald Prize, for outstanding contributions to the science of crystallography has been awarded to 1 woman and 14 men. That one woman is Prof Eleanor Dodson, one of many outstanding women in crystallography. .
Yet while crystallography has historically been a field dominated by men, the women who have been involved in crystallography over the years have pioneered this technique and made massive leaps in our understanding of crystallography.
As a crystallographer myself I wanted to introduce some of these women and the contributions they have made to this extraordinary field. So here are 4 crystallographer who have made outstanding contributions to crystallography.
Ada Yonath: pioneered work on the structure of the ribosome for which she she received the Nobel Prize in Chemistry in 2009. This also made her the first Israeli women to win the Prize.
Dorothy Hodgkin: pioneer of protein crystallography - one of the first people ever to take images of crystalline proteins. Hodgkin won the Nobel Prize in Chemistry in 1964 for her contributions to the field. .
Eleanor Dodson: A computational biologist and the lead scientist behind CCP4 (Collaborative Computational Project Number 4), the software tools used by protein crystallographers worldwide. Fun fact: Dodson attended the university I am currently completing my PhD at and was my poster judge earlier this year at a conference!
Kathleen Lonsdale: solved the structure of the benzene ring and confirmed that it was flat. She was a first for many accolades including being one of the first woman to be elected to the Royal Society, first woman who was tenured at UC London, first woman president of the IUCr and the first woman to be president of the British Association for the Advancement of Science.
The achievements of these amazing scientists make me proud to be a woman in crystallography!

y'all ever feel like you're an annoying brat or is that just me lol
