The document discusses the concept of a "patient fund" which would allow patients to directly donate and invest in medical research projects. A patient fund would segregate operating costs from project funding and allow patients to choose which specific projects their donations support through crowdfunding. It could help fill the "translational research gap" by funding high-risk projects ignored by other investors and take a long-term approach not focused on short-term returns. The proposed Fund My Medical Research non-profit aims to establish such funds to give patients more control over the development of new treatments.

This document provides an introduction to chemistry concepts and the scientific method. It defines chemistry as the study of matter, and matter as anything that takes up space and has mass. It distinguishes between mass, which is a measure of how much matter is present, and weight, which is a measure of gravitational force acting on mass. The scientific method is outlined as having five steps: making observations, forming a hypothesis, conducting experiments, analyzing data, and drawing a conclusion. Common variables and how to properly make observations are also discussed.
Simon the starfish has his arm cut off by a man with a chainsaw. However, he discovers that as a starfish he can regenerate his lost limb. Inspired by this, Simon decides to clone himself so that he and his duplicates can take over the world, and one year later he leads his army in a charge.
The muscular system functions to enable movement, maintain body temperature and posture. There are three main types of muscle: skeletal, smooth and cardiac. Skeletal muscle is voluntary and attached to bones, enabling movement. Smooth muscle is involuntary and found within organs. Cardiac muscle makes up the heart. Muscles work in pairs to contract and pull bones, releasing heat and maintaining homeostasis. Exercise causes muscle soreness through lactic acid buildup and microtears that later heal, leading to muscle growth.

A teacher gave students an exam problem to determine the height of a tall building using a barometer. One student answered by lowering the barometer from the roof with a rope to measure the length. The teacher was unsure whether to give credit since the answer did not show physics knowledge. When given another chance, the student provided multiple solutions, including dropping the barometer to time its fall using kinematics, comparing the barometer and building shadows, or marking the barometer's length up stairs. The student noted there were non-physics answers as well, such as trading the barometer to the superintendent for the building's height.
