Physicist demonstrates how to break a ruler with a newspaper and it's utterly delightful
Her enthusiasm is everything.

A simple sheet of newspaper can produce an enormous amount of force.
Have you ever had a teacher whose enthusiasm for their subject piqued your interest more than the subject itself? I had a biology professor in college who would talk in a low almost-whisper most of the time, but when she got excited about mitochondria or cellular respiration or the stages of mitosis, her voice would rise into a loud, high-pitched shriek. While her exuberance didn't make me fall in love with cellular biology, it did capture my attention and provide some chuckle-worthy entertainment while I was learning.
For people who don't have a natural inclination toward certain subjects, a passionate teacher can make all the difference. That's one reason a video of Texas A&M University (TAMU) physicist Dr. Tatiana Erukhimova explaining how atmospheric pressure works is so delightful.
Dr. Erukhimova has been teaching at TAMU for more than 20 years and is the co-author of an undergraduate textbook, "Atmospheric Thermodynamics: Elementary Physics and Chemistry." She is an award-winning educator, and when you see her physics demonstrations shared on TAMU Physics & Astronomy's YouTube channel, it's not hard to see why.
When most of us think of atmospheric pressure, we think about the weather. But Erukhimova demonstrates how atmospheric pressure can give a newspaper the power to break a ruler. (Sort of—the person actually breaks the ruler, but the newspaper is the key to enabling it to happen.) This demonstration would be cool on its own, but Erukhimova's energy is what truly makes the lesson.
Watch and enjoy:
(I may or may not be adding "Did I impress you? NO!" to my regular sayings.)
"Dr. Tatiana" has many similar videos, all of which have the same passion and enthusiasm. Watch her delight in making balloons shrink in liquid nitrogen and then come back to life.
And watch how she describes the "confidence and courage" you need to do a tablecloth inertia demonstration:
So much fun. Three cheers for teachers who make learning fun simply by enthusiastically sharing their wonder at how things work.

There's a reason why some people can perfectly copy accents, and others can't
Turns out, there's a neurodivergent link.

Have you ever had that friend who goes on vacation for four days to London and comes back with a full-on Queen's English posh accent? "Oooh I left my brolly in the loo," they say, and you respond, "But you're from Colorado!" Well, there are reasons they (and many of us) do that, and usually it's on a pretty subconscious level.
It's called "accent mirroring," and it's actually quite common with people who are neurodivergent, particularly those with ADHD (Attention Deficit Hyperactivity Disorder). According Neurolaunch, the self-described "Free Mental Health Library," "Accent mirroring, also known as accent adaptation or phonetic convergence, is the tendency to unconsciously adopt the accent or speech patterns of those around us. This linguistic chameleon effect is not unique to individuals with ADHD, but it appears to be more pronounced and frequent in this population."
Essentially, when people have conversations, we're constantly "scanning" for information—not just the words we're absorbing, but the inflection and tone. "When we hear an accent, our brains automatically analyze and categorize the phonetic features, prosody, and intonation patterns," writes Neurolaunch. For most, this does result in copying the accent of the person with whom we're speaking. But those with ADHD might be more sensitive to auditory cues. This, "coupled with a reduced ability to filter out or inhibit the impulse to mimic…could potentially explain the increased tendency for accent mirroring."
While the article explains further research is needed, they distinctly state that, "Accent mirroring in individuals with ADHD often manifests as an unconscious mimicry of accents in social situations. This can range from subtle shifts in pronunciation to more noticeable changes in intonation and speech rhythm. For example, a person with ADHD might find themselves unconsciously adopting a Southern drawl when conversing with someone from Texas, even if they’ve never lived in the South themselves."
People are having their say online. On the subreddit r/ADHDWomen, a thread began: "Taking on accents is an ADHD thing?" The OP shares, "My whole life, I've picked up accents. I, myself, never noticed, but everyone around me would be like, 'Why are you talking like that??' It could be after I watched a show or movie with an accent or after I've traveled somewhere with a different accent than my 'normal.'
They continue, "Apparently, I pick it up fast, but it fades out slowly. Today... I'm scrolling Instagram, I watch a reel from a comedian couple (Darcy and Jeremy. IYKYK) about how Darcy (ADHD) picks up accents everywhere they go. It's called ADHD Mirroring??? And it's another way of masking."
(The OP is referring to Darcy Michaels and his husband Jeremy Baer, who are both touring comedians based in Canada.)
Hundreds of people on the Reddit thread alone seem to relate. One comments, "Omfg I've done this my whole life; I'll even pick up on the pauses/spaces when I'm talking to someone who is ESL—but English is my first language lol."
Sometimes, it can be a real issue for those around the chameleon. "I accidentally mimicked a waitress's weird laugh one time. As soon as she was out of earshot, my family started to reprimand me, but I was already like 'oh my god I don’t know why I did that, I feel so bad.'"
Many commenters on TikTok were shocked to find out this can be a sign of ADHD. One jokes, "Omg, yes, at a store the cashier was talking to me and she was French. She's like 'Oh are you French too? No, I'm not lol. I'm very east coast Canada."
And some people just embrace it and make it work for them. "I mirror their words or phrase! I’m 30. I realized I start calling everyone sweetie cause my manager does & I work at coffee shop."
