Can you explain ECLIPSES ?

 

total eclipse

It’s your big chance to see the Sun’s CORONA.

You might have heard: there’s a TOTAL SOLAR ECLIPSE coming to the US on August 21, 2017.

Are you in the path of totality?

We’re so excited! We made a video explaining SOLAR ECLIPSES and LUNAR ECLIPSES.  Can you explain how these happen?  This is a great video to share with your friends and family before the big event. We describe what causes these two kinds of eclipses, and describe what you will see on the big day of the TOTAL SOLAR ECLIPSE. 

IMPORTANT SAFETY NOTE: YOU MUST WEAR ECLIPSE GLASSES. 

You must, must MUST get some safety glasses.

★★★VERY IMPORTANT SAFETY NOTE★★★
Many fake eclipse glasses have been sold on Amazon.com

Have we been sucked into a black hole? YES!

Black holes have captured imagination since they were first proposed as “Dark Stars” – massive objects with so much gravitational pull that nothing can escape – not even light.

At the time, the most expensive Disney movie ever.

Did you see the Disney movie back in the day? We saw it as children, and that might have had something to do with why we HAD to make this video. That and our physics professors in college describing the process of “noodling out” – stretching and stretching as you are sucked in to a black hole.

One of our much-admired professors from Caltech, Kip Thorne, served as the science advisor for the film Interstellar.  This movie gave the best visual description to date of a black hole, and it inspired our work here.

We’ve been working on this one for quite a while. It’s our most ambitious video yet. Please share it with all the stargazers you know.

In Search Of: Our Missing Female STEM Viewers

Socratica is an educational YouTube channel, focusing mainly on STEM. We do have some Arts and Humanities in the mix, but STEM is what we think of first.

There’s a lot of talk in the news and on school campuses about the lack of women in STEM. Is it due to subtle gender bias, overt gender bias, harassment, work policies incompatible with having a family, lack of interest, “leaky pipeline” – is it none of the above or all of the above?

As a STEM person with two X chromosomes, I’ve never doubted that STEM was for me (it’s still my passion, even though I’m not doing research anymore). I read scientific journals, I watch STEM videos, and I make STEM videos. So how come my videos aren’t getting more views from women?

Just look at our channel statistics:

Overall – 69% male, 31% female:

overall-demographics

But wait, it gets worse.  For a video on Neutron Stars, 91% male, 9% female:

neutron-stars-demographics

We always knew we had predominantly male viewers (our comments are almost all from men), but the stats for our neutron stars video frankly shocked me. Our videos are clear, concise, friendly, and more often than not, presented by a woman. Most of our videos are written by women.  And yet, where are our female viewers?

If you are someone who is concerned about the lack of women in STEM, please share our videos with the women in your life. Get the word out. Science is for everyone. Socratica is for everyone. We need more viewers of all stripes, but there is just no reason why women shouldn’t be loving our videos just as much as men.  Come on.

For COSMOS lovers: What are neutron stars?

All of us at Socratica grew up watching Carl Sagan and his groundbreaking series Cosmos.  Most people think of it as a series on astronomy, but it was really more about our place in the universe as thinking, exploring creatures looking to understand who we are and how did we get here.

When I taught biology, I regularly showed Sagan’s episode about evolution as an introduction to the topic. My students would laugh about his pronunciation of “yooman” and his odd speech patterns with unexpected….PAUSES. But by the end of the episode, they were completely won over and wanted to see more of this fascinating man.

Sagan and his tree

This line always got a big laugh.

Carl Sagan’s enthusiasm and broad knowledge of so many subjects made us want to learn almost everything from him. The work we do at Socratica is maybe best considered an homage to great teachers like Sagan.  There’s no way we could ever capture his special sauce – but we do get inspiration from his candor, his love for teaching, and his quest to know.

We’re over the moon to start a new playlist on Astronomy. Our first video:  What are Neutron Stars?

 

Over the moon, see what I did there? I crack myself up sometimes.

 

We recommend, obviously:

Imagine if TV adverts actually inspired you.

How often do you see an advertisement that you wish were longer?

Today, I saw an advert that was like a mini sci-fi film. I wish I could see more – I wish it were part of an actual film. Amazing what you can do in under 10 minutes. (Nice to see “Littlefinger” in something so positive.)

Can you imagine if you wanted to stick around for the advertisements on TV, because they were actually enjoyable?

Can you imagine if adverts were a net benefit – they made you feel good about yourself and humanity, and encouraged you to think big and achieve?

I’m filing this one away for future reference for those days when I fear that all media is playing to the lowest common denominator.
