@girl_in_physics @IOPPublishing Congratulations Meriame!

[Alan Fry @LCLS_alanfry]

@melioratus Your mom is awesome, Brian.

[Alan Fry @LCLS_alanfry]

It was great fun hosting you, Dianna, and we look forward to your next visit!

[Dianna Cowern @thephysicsgirl]

I went to @SLAClab for the first time yesterday! There is SO much research there, I see videos in my future...

Which book should I read for learning research in experemental physics? by Alan Fry https://t.co/8uMY1fUDDz

[Alan Fry @LCLS_alanfry]

Have reading Stephen Hawking's books and with little math and physics knowledge, what are some good books in important subjects of modern physics (like quantum mechanics) that I could read while in vacation? by Alan Fry https://t.co/921A1BEYt4

[Alan Fry @LCLS_alanfry]

Got to give this a try on the LCLS-II photinjector laser. https://t.co/o13ulvfPMQ

Registration is open for 46th SLAC Summer Institute, an annual 2-week-long "summer school" including lectures, topical conference talks, discussion sessions, student projects & tours; this year's focus is "Standard Model at 50: Successes and Challenges" https://t.co/UtLB1WtQ13

Ahem, photons delivered the heat from the oven to the pizza (thanks for generating us, electrons!). 7.32 µm for the win! #TeamPhoton #subatomicsmackdown https://t.co/P7w8H441OY

[Greg Boebinger @gboebinger]

The Electron heated the pizza oven. And the Neutron made the pepperoni possible....well known fact that pepperoni is an isotope of salami. #SubatomicSmackdown #TeamElectron #TeamNeutron

[Alan Fry @LCLS_alanfry]

Also, so very, very slowwwww...

The trouble with electrons? Too negative. The trouble with neutrons? Always running away. The trouble with protons? They repel each other. The answer is shining out at you all! #ChooseLight #TeamPhoton @SLAClab @symmetrymag https://t.co/XxYnEK7GU1

[Alan Fry @LCLS_alanfry]

Don't get me started on their half-hearted spin... https://t.co/pZsAlBYD3O

Star light, star bright,
First star I see tonight,
I wish I may, I wish I might
Have this wish I wish tonight...

...to crush my fermionic rivals in the Subatomic Smackdown.

RIP @StephenHawking. Thanks for proving that photons will eventually claw the universe back from black holes, one photon at a time.

I reckon we can all agree on this: black holes suck. Thanks to X-rays and gravitational lensing for informing us about these galaxy-destroying, nightmare-inducing, cosmic death-holes.

Einstein’s Annus Mirabilis (1905): (explanation)
1. Photons liberate electrons from metallic prison
2. c is constant no matter how fast your little train goes
3. Fermions will one day become photons
4. Atoms are real! Named after composite color
