Break a Ruler With Atmospheric Pressure!

Dr. Tatiana Erukhimova demonstrates how atmospheric pressure can break a ruler with physics. When spreading out the newspaper on top of the ruler, Dr. Tatiana basically creates a large suction cup by preventing air from flowing underneath. When she strikes the ruler, it tries to lift up against the newspaper, but because the air can’t flow fast enough into the space between the table and the newspaper, most of it pushes down on the newspaper (and the ruler). All that weight on the ruler causes it to snap.

Came from Daily Dose of Internet. This doctor has so much energy when presenting that I absolutely adore her!

She's breaking the ruleRs of physics.

I LOVE THIS LADY!!!
We need more videos of her!
I want to binge watch her videos!!

[jim]

Love this, she's engaging. A quick simple lesson in physics. I bet she could teach even the most boring of subjects/lessons and still grab attention. Props to her!

[deeeeeeeeeeeeeeeeeeeeeeeee]

I love her so much, anybody who has her as a teacher is truly blessed 😭

[abandonedaccount]

that's crazy, , it's so weird how a small piece of paper can be the difference!

Thank you for posting! Great energy and passion for teaching

Respectfully, I propose that the explanation given in the video could be revised to be more accurate. Air pressure (7000 lbf) IS acting on the paper as stated, but on BOTH SIDES of the paper, thus having no net effect on the paper.
A more accurate explanation for the phenomenon would be that the viscosity of the air prevents the paper from moving at high speed. The air does not readily move quickly, which then prevents the paper from moving quickly through it. The ruler alone can move through the air easily because it has less surface area moving through the air. This is alluded to in the video, but is presented alongside the other less relevant information.
Although air pressure and viscosity of the air are correlated, the static air pressure is not the reason for the ruler breaking.
This is more of a fluid dynamics phenomenon than one of static air pressure.

All that said, this professor clearly knows how to reach students (and the public) with an interesting video on physics. Her enthusiasm is more of what we need to get people interested in science.

I would pay money for this lady to be my teacher. She is amazing. I wish every teacher had this much energy. We definitely need more people like her on earth.

My son and I absolutely love watching Dr. Tatiana, we need more teachers like her in our life! <3

[Gandi]

I love your enthusiasm! I think "did I impress you?... No" will become a stable saying in our house 😂

[AuraQueenDraconis]

She is the BEST teacher I've ever seen! I only want to learn physics from her from now on!! 😁

[queenknow]

Absolutely LOVE this woman… her enthusiasm is contagious! Brava!

The atmospheric pressure is not the reason because it pushes both sides of the paper. The air viscosity is the reason.

Came here from Reddit. Subbed for more science lessons.

[dystho]

Thank you for these videos!
Your enthusiasm is contagious! I love it

It doesn't take much to eyeball an outstanding, passionate and devoted teacher, especially Physics ones

[antoferrada]

I came here from a Tumblr post and I feel so lucky to bump into it. I love people who are passionate while talking about something they like, she really inspires me and makes me interested in physics! Watching her videos makes me happy, I can genuinely feel her joy and excitement as she is thrilled explaining how it works.

If all my teachers were this energetic in teaching when I was growing up i would have gotten straight As

Congratulations!!!! This channel is amazing!
