Hey all, let us have a look at some basics of optics and light science today! #phdchat #Physics #optics
Let us look at some common objects that can be used to understand the nature of light rays. This includes mirrors and lenses. #phdchat #physics #optics
Light travels in a straight line. It is the most fundamental property of light. An obstruction on the path may only change its direction, else it travels in a straight line. #phdchat #optics #light

Why Mueller’s press conference is complete bullshit and he debunked The Democrats Russian hoax and his own report /1
in his own words “ there was no evidence to establish a conspiracy”, “ The Report is his final word and testimony”, “ there is not sufficient evidence to charge a broader conspiracy”

None of the Russians involved were related to the Russian govt except the ambassador /2
Trump is quite the mastermind when it comes to “colluding” he was able to conceal this from everybody, including 50 FBI investigators and Mueller. Trump is such an idiot and a loser, but he was able to work against our country with the top levels of government (lmao smdh) /3

Just launched, the @OpticalSociety & @SPIEtweets Professional Conduct @WomenInResIE joint report on Assessing and Addressing The Level of Harassment at Scientific Meetings #STEM #womeninstem #womeninoptics #scicomm #optics #photonics spie.org/about-spie/adv…
Some interesting stats, which are not very surprising "over 9% of respondents say they experienced harassment at meetings or events hosted by the scientific societies. Of those who experienced harassment, 63% were women." #womeninstem #womeninoptics #LGBTinSTEM #optics #photonics
I've just had a quick read but the thing that struck me most, more than the stats was the personal stories in Appendix I - sadly these are stories I've heard from friends & colleagues who have attended scientific meetings & conferences. #womeninSTEM #womeninoptics #LGBTinSTEM

#Inktober index card 1: Relative dating is a snippet of simple magic. As soon as you stop to think logically, entire landscapes unravel in eagerness to tell you their story. #sciart #geology #teaching
#Inktober index card 2: #DonnaStrickland is the 3rd woman to EVER win the #NobelPrize in #Physics for her work on chirped pulse amplification, an engineering #optics technique to create short, intense laser bursts with broad industrial & medical applications. #sciart #cansci
#Inktober index card 3: I’m #TeamIce for #MinCup2018, infatuated with this simple & elegant mineral.

Here’s my interpretation of ice from chemical composition to melt molecules to crystal hexagons. I couldn’t find my blue pens for sketching the #thinsection. Shush.

Vote ice!

Okay, let’s do some fun #optics trivia! Lessee... to start, my favorite: 2 meters squared of concentrated sunlight is enough to melt stone.
#Optics trivia: even in vacuum, light can travel slower than the speed of light! Beams with a “twist” in them can be slower, because the light is following the “twist,” not the straight line path. sciencenews.org/article/speed-…
#Optics trivia: optical tractor beams, which can trap and attract objects, do exist! ... but they can only trap stuff the size of bacteria. ekvv.uni-bielefeld.de/blog/uninews/e…
