Buckle in, everyone. I'm about to take you on a journey through the 20th century into modern times, and I'll be talking ocean exploration all the way. Let's get right to it, because the last century has been a whirlwind of tech and discoveries.
Yesterday, I left you with Alexander Agassiz’s coral reef studies in the Pacific, which took 6 years and investigated areas previously too remote for most Western explorers. Today, we begin with the year 1900 and the first modern submarine.
In 1900 A.D., the US Navy accepted its first submarine, the Holland. This sub was built by New Jersey native John P. Holland and had two motors - an electric one while submerged, and a gas engine on the surface.
Hey hey hey! Good evening to everyone! You wouldn’t believe how busy the last two days have been, but I promise I’m about to make up for it – I’m going to tweet about how friggin awesome ocean exploration really is. Plus some volcano stuff, obvs.
Personally, I’ve been fortunate enough to board two research vessels - the R/V Roger Revelle and the E/V Nautilus. These cruises took me to, respectively, the Lau Basin (black smokers!) and Kick’em Jenny (undersea volcano!). (Photo: Kick'em Jenny vent, c/o @EVNautilus )
Today’s (ok, yes, tonight’s) thread will be on the history of humanity’s achievements in marine exploration, starting all the way back in the time of the Greeks. Tomorrow, I’ll go into the more modern-day stuff, e.g. recent discoveries and exploration methods.
My work looks at how we can use quantum mechanical simulations to describe the interactions between the building blocks of materials; sometimes atoms, but more often now nanoscale clusters or layers...
So My Heart Will Go On is the clear winner of the poll, despite the other two songs being much, much better. But, in the name of unbiased science, we'll analyze The People's Favourite AND I WON'T EVEN COMPLAIN EVEN.
I talked to the family, they all say "hi, people on the twitter", and now it's time for a little bit on the EVOLUTION OF MUSIC.
SO. We talked a bit about the limbic system and how one of its jobs is to reward us when we do survival-y things.
Also the limbic system:
So if music is in there as a reward, and it isn't chemically adding anything to the body (like drugs of abuse), or isn't designed (debatable) to be addictive (like gambling, certain *evil* internet games), what is it doing in there?!
I had a conversation with a friend (and mentor) a few years ago wherein she said, "A scientist who isn't a philosopher isn't really a scientist at all." It has stuck with me since.
I'd love to know what you all think about it.
Even though a PhD means a Doctorate in 'Philosophy', many of the PhDs don't know WHY they're looking at a question and spending 3-10 years of their lives working on it. Yes, they might have a specific goal with well thought-out objectives, but what about the reason?
All the MSc students at my university were called to attend the thesis defense of a PhD candidate. She had worked on industrial waste and the microbes found in the vicinity of places from where the effluents were discharged.
[Transformation&Representation] Before diving into today’s topic of transformation and representation. I would like to run a series of polls. Please feel free to participate!
1. Are you currently working in a STEM (science, technology, engineering, maths) field?
2. If you are in STEM (student or employee or any STEM involvement), are you a minority? (Minority here is defined as any group that is underrepresented, includes race, gender, disability, sexual identity or orientation etc)
I am really passionate about this topic because I am a minority in my field. I am a minority because I am a woman. I am a minority because I am an African researcher. I am a minority because I am of colour. #womeninSTEM#POCinSTEM#AfricanSTEM
[Intro thread] Hi everyone! My name is Kim @KimTommy92 and I have recently completed my Masters degree @WitsUniversity in palaeoanthropology! I decided to take a year off before starting a PhD and I am currently the science communication officer for @CoE_Palaeo!
I’m joining you today from my home in Johannesburg South Africa 🇿🇦. #ProudlySouthAfrican. My home country has a rich and beautiful fossil record and you might already know the names of the hominins I research.
As I mentioned I am a palaeoanthropologist so I study the evolution of our species modern humans. This is a really broad field with many amazing researchers looking at the questions “Who are we? And where did we come from?” from a variety of different perspectives.
Good morning sci-tweeps. Let’s start off the day by talking about one of my hobbies: the neuroscience of baseball (aka- why is it so darn difficult to hit a baseball?) 1/25
Sometimes I’m accused of being a poor cognitive scientist. Why I don’t study “real” (aka- complex) cognition, like how we play chess or learn a second language or solve math problems? Why study something as simple as whether or not to make an action? 2/25
But if you really take a step back and look at it, deciding to swing at an oncoming pitch is really an impressive computational feat.
So let’s take a moment to consider all the process that go into solving the “simple” problem of swinging at a baseball. 3/25
Before I leave this account, I'd like to share some final thoughts. As you may know, global temperatures have been gradually increasing since the Industrial Revolution, primary driven by a greenhouse effect caused by increasing atmospheric CO2 from human activity. #climatechange
Greenhouse gas emissions have many sources - some of which are natural, but most are the result of human actions like deforestation, burning fossil fuels, and agriculture. Certain soil cultivation practices, fertilizer use, and livestock are significant contributors to GH gases.
Red meat in particular, lamb and beef, contribute significantly more greenhouses gases per pound of meat produced than other other source of food. One pound of beef generates more CO2 than 1 gallon of gasoline burned.
Yeah, we're going to talk a little about this.
I do a lot of remote wilderness #fieldwork looking for dinosaur bones & tracks in B.C., and I never feel more secure than when I'm among the bears, hours from people.
I exist in a rather sparsely populated area of B.C., but a large percentage of that population is involved in industrial work.
I have visited many industrial sites.
It's sad that I'm no longer surprised to see pics of nude women in smaller outbuildings.
The fact these images exist on industrial work sites demonstrates to me *exactly* the level of respect I or their women coworkers can expect: that I'm just a thing that exists for their amusement.
So I left #postdoc, and I left #adjunct and went into #industry. There are two things I wish I knew when making this transition, and I hope it may help you...
...I didn’t know what buzzwords to put on my resume to make it reflect, in #industry terms, my skills. For #STEM academics, I’ve learned that a lot of what we do includes systems engineering, and project management...
...now this may be obvious to some of you, esp the E part of #stem, but I didn’t know this. I recommend looking up buzzwords for sys eng and project management...
