I used to struggle with understanding calculus. The only study method I used was passively consuming the material by re-reading and highlighting my notes. I thought it was helping me retain what I studied, but it left me with an 83% grade on my exams.

I stumbled across this method online and started learning how I could apply it to study calculus effectively. The recall loop system shifted my results from an 83% to a 97% in calculus while also cutting down my study hours.

Here is how I completely mastered calculus topics using this method:

- Read the topic. Usually, I take 60 minutes to understand the main concept and afterward, I jot down the key points. I do one quick pass over a concept and write down just the primary formula behind the material.

- After studying, I slide my notes away, pull out a blank sheet of paper and solve a problem or write down the steps without relying on my notes. This part is important for actively recalling what I studied in a specific calculus topic.

- I check my notes and identify what I missed or got wrong during the active recall process. I circle it with a red marker so I know what I need to relearn and review.

- Repeat the loop. Rather than re-reading the whole section, I focus strictly on the steps where I made mistakes. Then I read those parts again, close my notes and solve a fresh problem until I get everything correct.

This helps me actively learn the topic thoroughly rather than just passively studying. Passive studying will not work in subjects like math and science. Use an effective method that forces your brain to recall information and test yourself in short loops.

I built jevos-1b: send a text and a yes/no question.

One forward pass, no text generated.

• Runs on a laptop CPU with llama.cpp: 54 ms short request, 220 ms long one. No GPU, no API.
• Speaks Jev's API format, so Jev SDK code works unchanged for yes/no questions.
• On 2,000 yes/no questions about rules it never saw: Jev 0.927, jevos-1b 0.815, Laya 0.489. Slower models are still more accurate, it's a trade-off.

A man came into hospital with both legs numb, cold, and increasingly paralyzed, and a scan revealed the cause wasn't neurological at all. Years of undiagnosed constipation had let stool build up in his colon to the point where it had massively distended his large intestine, and that swollen mass was physically pressing on the iliac artery, the vessel supplying blood to the legs.

Cut off the blood supply for long enough and the tissue starts to suffer, which is exactly what was happening. The condition itself, called abdominal compartment syndrome, is normally associated with trauma, major surgery, or severe pancreatitis, so a case caused purely by fecal buildup was unusual enough to warrant its own case report. Doctors put him under general anesthesia and manually removed roughly two liters of impacted stool to relieve the pressure, and he needed 13 days before he could walk again, then close to three weeks total in the hospital.

I usually studied for 3-4 hours a day when I first started pursuing pre-med, and I felt like I didn't really retain much of what I studied. Recently, I saw a lot of people posting their achievement of studying for 10+ hours in a single study session. It is actually insane to think people can grind through studying for such long hours.

I want to try it and see if it is worth studying that long. Would you recommend studying that long if you're in a pre-med course and how effective do you think it is?

Sounds like some superhero story, right? But this actually happened to a man called Roy Sullivan, an American park ranger who holds the Guinness World Record for surviving the most lightning strikes.

And no, he wasn't struck seven times in one day.

His first recorded strike happened in 1942 when he was working as a ranger. Then over the next few decades, lightning kept finding this poor guy again and again.

He was struck in 1942, 1969, 1970, 1972, 1973, 1976 and 1977.

And somehow, he survived every single one.

The strikes still caused him plenty of injuries though. He suffered burns, lost some of his hair, and had other injuries from the different incidents.

One of the strangest things is that some of these strikes happened in places where you would think he was safe. In one incident, lightning apparently hit him while he was inside a ranger station.

And in another, he was fishing when lightning struck him.

After being struck so many times, he even started carrying a can of water with him because his hair would apparently catch fire when lightning hit him.

Maybe nature just had a personal problem with him.

But there is also a sad ending to his story.

After surviving all those lightning strikes, Roy Sullivan died by suicide in 1983 at the age of 71.

It's honestly hard to believe one person could experience something as unlikely as surviving seven lightning strikes and still have such a tragic ending to his life.
