What’s the difference between astronomy and astrophysics?

Technically speaking, astronomy is the science of measuring the positions and characteristics of heavenly bodies, and astrophysics is the application of physics to understand astronomy. However, nowadays, the two terms are more or less interchangeable since all astronomers use physics to understand their findings.

9 Things You Shouldn’t Do on an Empty Stomach

Image
“You are what you eat” is an adage known to everyone. But what we do before a meal also has a great impact on our health. I am going to tell you about 9 things you can’t do on an empty stomach (no less than 2 hours after your last meal). As a bonus, you’ll find information about what you can do when you’re hungry at the end of the article. 9. Take anti-inflammatories Aspirin, paracetamol, and other nonsteroidal anti-inflammatory drugs (NSAIDs) can’t be taken on an empty stomach. Not only does it reduce their effectiveness but it causes serious health problems (such as gastric bleeding) as well. Read here about other medicines not to be taken on an empty stomach. Advice: Milk lowers the negative effects of NSAIDs. If it’s not available, you can wash the drug down with plenty of water. 8. Drink coffee Even decaffeinated coffee stimulates the production of acid that might cause heartburn and other digestive tract issues if drunk on an empty stomach. Skipping breakfast even after c

Introduction In digital logic design, circuits fall into two categories: combinational logic and sequential logic . Combinational logic circuits are implementation of Booleanfunctions. They compute their outputs as functions of theirinput . They do not have any memory elements. Sequential logic circuits, implement functions with state .That is, they keep information internally (think of this informationbeing stored in data members of an object). The output of a sequentialcircuit depends not only on the input bits, but also on the internalstate. It turns out, for sequential circuits, it’s easier to designwith a clock. So, what’s a clock? Most people think of a clock as a way to tell time. Why woulda computer need to know how to tell time? A clock, on a computer, isn’t the same kind of clock usedin your home, or on a watch. If you’ve ever bought a computer,one of the more important features it the clock rate. For example,you may buy a machine that’s running at 2 GHz. Do you knoww
