What did you learn today?

Today, I started learning how to crochet mini mushrooms. If I end up completing it, will show y'all ?

Sounds fun!

Today I learned about the term Battleshort.

TIL bullet timer.

Fyi it is just bullet time -er, as in someone that can go into bullet time slowmo aka reacting and travelling fast as bullet.

I still think the term is stupid.

I learned that staying up for 24 hours on 2 energy drinks and suffering through an appointment after sleeping 50 hours over the 3 days prior will fuck you up… Nyaa~

A lesson all must learn at least once in their life.

Methane from cow digestion and manure is more harmful to the ozone layer than car emissions.



Methane is a potent greenhouse gas that can indirectly affect ozone depletion by altering atmospheric chemistry, particularly by increasing water vapor in the stratosphere, which accelerates ozone-destroying reactions. It has a global warming potential about 25-28 times that of CO2 over 100 years, and its atmospheric lifetime is around 12 years.
Cars primarily emit CO2, NOx, and other pollutants, which contribute to ground-level ozone (smog) but have a less direct impact on stratospheric ozone depletion. Historically, chlorofluorocarbons (CFCs) were the primary ozone depleters, but methane's role is significant today due to its chemical interactions.
Livestock farming globally emits about 80-100 million metric tons of methane annually, while cars contribute a smaller fraction of ozone-relevant pollutants. So, cow methane has a bigger impact on the ozone layer than car emissions.
----------

Cow Methane Emissions: Cows burp out methane gas (CH₄) when they digest food. In 2025, all the cows in the world make about 100-120 million metric tons of methane each year. Methane doesn’t really hurt the ozone layer much—it mostly makes the Earth warmer. Its effect on the ozone layer is super tiny, like less than 1% of the damage done by other gases.

Plane Emissions (NOx): Planes, especially jets, release nitrogen oxides (NOx) high up where the ozone layer is. In 2025, planes emit about 5-6 million metric tons of NOx. NOx directly attacks the ozone layer, breaking it down. It’s a bigger problem for the ozone than methane. Studies say plane
NOx can cause about 0.5-2% ozone loss in busy flight areas.

Comparing the Danger: Plane NOx is way worse for the ozone layer than cow methane. Methane’s effect is so small it’s almost zero, while NOx actively eats away at the ozone. Planes are roughly 50-100 times more dangerous to the ozone layer than cow methane in 2025, percentage-wise, because NOx directly damages the ozone where it’s released, and methane doesn’t.

Final Answer: In 2025, planes emit 5-6 million metric tons of NOx, which is about 50-100 times more dangerous to the ozone layer than the 100-120 million metric tons of methane from cows, which barely harms the ozone at all.

Today I learned that the word is "harebrained", not "hairbrained." I always thought it was supposed to be calling someone brainless, like you're so stupid that you've got hair growing inside your skull where your brain should be.

A healthy horse can produce significantly more than 1 horsepower for short bursts. Studies and anecdotal data suggest with a sprint or jump, a horse can generate up to 10–15 horsepower during intense, short efforts (e.g., a gallop or pulling a heavy load briefly). This is based on calculations of muscle force in Thoroughbreds or draft horses during maximal exertion, where peak forces can exceed 2,000 pounds for a few seconds.

Draft horses (e.g., Clydesdales, Percherons) can sustain about 0.8–1.5 horsepower over hours when pulling loads. Historical data from agricultural work shows a draft horse can pull around 10–12% of its body weight (e.g., 180–240 pounds for a 2,000-pound horse) at a steady pace of 2–3 mph for 6–8 hours.

James Watt’s original estimate of 1 horsepower was based on observing horses lifting coal or turning mill wheels, averaging their sustained effort. He estimated a horse could lift 330 pounds 100 feet per minute (33,000 foot-pounds/min), but this was conservative.

Modern tests (e.g., dynamometer studies) show horses can exceed this briefly. For example, a horse pulling a sled with 1,000 pounds of force at 4 mph generates about 2.7 hp (1 hp = 375 pound-feet/second).

Horses risk injury or exhaustion if pushed beyond their aerobic threshold for too long. Safe daily work typically stays below 70–80% of max capacity. Overloading (e.g., pulling >15% of body weight for long periods) can cause lameness or metabolic issues like colic.

TIL that there is a third season for The Breaker and it is named Eternal Force.

After the disaster known as New Waves, no. Just no.
