What was it that your child told you that gave you chills?

When my daughter was younger, she had once told me of this man named Tyrone that was sitting on her bed in a black suit and tie and asked if she had Cool-Aid and cookies. She said she went to the bathroom and when she came back he was gone. She wanted to know where he went. The description was my brother that had passed away when I was five years old. He was 34 when he passed and he wore a black suit and tie when he was lying in his coffin. We used to share Cool-Aid and cookies when he would come over to visit.It wasn’t chilling to me at all. I was thrilled to know that my brother stopped in to see my daughter.

You told me about a solar eclipse, is there a lunar eclipse?" Said Varisha, who had been listening for a long time. "Yes, son! There is also a lunar eclipse. When the shadow of the earth that falls between the earth’s moon and the sun during its rotation falls on the surface of the moon and the moon becomes dark, it is called a lunar eclipse." Because both the earth and the moon receive light from the sun. The earth revolves around the sun in its fixed orbit and the moon comes twice a year and its shadow falls on each other, if the moon falls on the moon then the lunar eclipse and if it falls on the sun then the solar eclipse is visible on the earth. Now everyone sit in the room and have breakfast.

Thermocouple

According to the See beck effect (also called the thermometric effect), a temperature gradient along a conductor induces a voltage across the conductor. However, measuring this voltage involves attaching a second conductor to the hot end, which will see its own voltage induced and cancel out the voltage we wished to measure.

Fortunately, the relationship between temperature difference and voltage varies with materials, so by using a second conductor made of a different material, a small voltage difference can be found at the ends. This device, a two-terminal element consisting of two different metal wires joined at the end, is called a thermocouple.

The effect is weak, typically 10’s of microvolts / ○C, but can be amplified to a more useful range. Thermocouples operate over a very wide range of temperatures, are inexpensive (just two pieces of wire), and can stand up to harsh conditions.

You can make your own thermocouple by joining two wires of dissimilar metals. If the wire is thin, they can respond to temperature changes very quickly.

Thermocouples measure the difference in voltage between two points. To know the absolute temperature at a given point, one must know the temperature at the other point. we measure the temperature at the hot junction at the tip of the thermonuclear where the two metal wires are joined. up to harsh conditions.
