It's AumSum Time How were the pyramids built? Using Alien Technology. Oh. Just listen. The huge stones used to build the pyramids. Were carved hundreds of miles away from the
actual site. Egyptians were yet unaware about wheels. So, how did they transport these huge blocks? By using sledges. How do we know this? An ancient wall painting shows 172 men. Hauling a massive statue on a sledge. Now, pulling sledges on sand would be difficult. Because the sand would clump in front of the
sledge. Increasing friction and requiring more force
to pull it. However, the intelligent Egyptians had a solution. In the painting, we can see someone pouring
water on sand. Adding right amount of water to sand reduces
friction. Requiring only half the people to pull it. Also, cranes hadn't been invented yet. Thus, Egyptians built huge ramps to stack
the stones on top of each other. Creating this architectural masterpiece. Has the Bermuda Triangle mystery been solved? The Bermuda Triangle is roughly a triangular
region of the Atlantic Ocean. Between Bermuda, Florida and Puerto Rico. Here, many ships, boats, planes, etc. Have reportedly disappeared under mysterious
circumstances. According to a recent study. Experts theorize that a natural phenomenon
known as rogue waves. Are the main reason for some of these mysterious
disappearances. Rough stormy seas of this region. Can create rogue waves which are about 100
feet high. These high waves can easily damage ships and
boats. Another theory states that hexagonal clouds
found in this area. Can act like air bombs, blasting winds at
huge speeds. These winds can destroy planes and create
waves which can destroy ships. Some people believe that a strange magnetic
anomaly affects the compass readings. Thus misguiding ships and planes. Others even attribute the events to UFOs or
aliens. What is constipation? After much of the digestion and absorption
of nutrients. The unwanted food or stool which is in a liquid
state. Flows to the large intestine or colon. Here, by means of a series of muscular contractions
and relaxations. The stool is pushed or moved through the colon. As the stool moves, water is absorbed from
the stool, making it more solid. Finally, the stool enters the rectum. When the rectum is full and stretched. The nerves of the rectum send signals to the
brain. At this point, we decide whether to expel
the stool or retain it. Going to the toilet and expelling the waste
is a part of our daily routine. However, sometimes due to slow muscle contractions. The stool passes slower than usual through
the colon. As a result, excess water is absorbed, making
the stool very hard. Such a condition in which an individual has
hard stool. That is difficult to expel is called constipation. Why is it hard to cure Alzheimer's disease? Alzheimer's disease is an irreversible, progressive
brain disorder. It basically occurs when proteins in the brain
malfunction. And clump together forming plaques and tangles. These plaques and tangles block communication
in between brain cells. And even cause cell death. Thus leading to memory loss, mood changes,
hallucinations, etc. Now, it is hard to cure Alzheimer's because
symptoms of the disease. Begin to show when it has almost irreversibly
damaged the brain. Also, finding candidates for effective clinical
trials is difficult. Because there is no method to identify people
with the disease at initial stages. Thus, it is hard to test the medications and
check whether they work or not. In addition to this, Alzheimer's affects different
people in different ways. Hence, a drug which is somewhat effective
on a patient suffering from Alzheimer's. Might not work on another patient. In short, due to a lack of fundamental understanding
of the disease. We are unable to cure Alzheimer's.
