The students who graduate with the biggest head start are not smarter. They just found the right tools earlier.
Most people use NotebookLM the wrong way.
They ask for summaries and get mediocre results.
Here are 10 advanced NotebookLM prompts to help you learn faster, think deeper, and actually understand your sources.

I remember reading "Felson’s 10 Axioms for a Lifetime of Learning Medicine" as a student
From Felson, B. Humor in Medicine, 1989; RHA Inc., Cincinnati, Ohio.
And from Goodman LR, Felson B. Felson's principles of Chest Roentgenology: A programmed text. Amsterdam: Elsevier; 2020.
(1/4) you know we like to have a good time over on https://t.co/ubmwEnBR61, but we are also in the business of occasionally creating Serious Medical Educational Tools™
so with that in mind, i present a new EEG learning tool:
THE EEG MACHINE 🤖🧠⚡️

The Solar Zenith Angle is the angle between the sun’s rays and the vertical line directly above you. When the sun is directly overhead, the angle is zero degree.
Most people miss out on Vitamin D because they head out when the sun is too low. For your skin to produce Vitamin D, it needs UVB rays. However, UVB rays are easily absorbed by the Earth's atmosphere/pollution.
While many people prefer the gentle rays of the early morning (7:00 AM – 9:00 AM) because it’s cooler, those rays are mostly UVA. To get a therapeutic "dose" of Vitamin D, you ironically need the midday sun that most people try to avoid.
When the sun is at an angle of 45° or less from the vertical, the path through the atmosphere is shorter. This allows UVB rays to reach your skin.
The Shadow Rule
A quick way to check the Solar Zenith Angle without a calculator:
• Shadow shorter than you? You’re making Vitamin D.
• Shadow longer than you? The atmosphere is blocking the UVB rays.
The Sweet Spot
In India, this "high sun" window is usually 11:00 AM to 3:00 PM. Even 15 minutes during this time is more effective than hours spent in the early morning or late afternoon sun!
🧠 The traditional "black-and-white" core vs. penumbra model for acute ischemic stroke is outdated!
A new review proposes a 6-level continuum to better map the dynamic nature of cerebral ischemic injury and improve personalized reperfusion decisions:
1️⃣ Benign Oligemia: Mild hypoperfusion, no infarct risk.
2️⃣ Vulnerable Oligemia: Mild, but can transition to penumbra if physiological conditions change.
3️⃣ Durable Penumbra: Moderate hypoperfusion, viable for a longer time but needs eventual reperfusion.
4️⃣ Critical Penumbra: Severe hypoperfusion, demands urgent flow restoration to survive.
5️⃣ Nonleaky Core: Irreversibly injured, no benefit from reperfusion
6️⃣ Leaky Core: Irreversibly injured with early blood-brain barrier disruption—huge risk for hemorrhagic transformation and malignant edema if reperfused! 🩸⚠️
Moving beyond a binary model helps us maximize EVT and IVT benefits while avoiding harmful treatments in the leaky core. ⏱️⚕️ #NeuroTwitter #Stroke #Neurology #MedEd
