# Why A Mechanical Calculator Tries To Commit “Suicide” When You Divide By Zero?

Short Bytes: What happens when you try to divide by zero on your computer or phone. It gave an error on my computer and showed infinity on my smartphone? But, what if you divide by zero on a mechanical computer? Well, the result is scary and you need to watch it yourself to believe it.

Do you remember your early mathematics classes when your teacher taught you the rules of multiplication and division? Your teacher might have told you that you can’t divide any number by zero as the answer is infinity and your calculator shows error or infinity.But, if you try the same on a mechanical calculator, the device goes berserk and you see something worse than an error message. In the video shared below, someone attempts to divide by zero on a mechanical calculator Facit ESA-01 and the outcome is scary.

## , what does a mechanical calculator try to commit suicide?

The mechanical calculator basically performs division and multiplication by subtracting and adding, thus division is simply a sequential subtraction.

For example, dividing 10 by 2 is basically —

1. 10-2=8
2. 8-2=6
3. 6-2=4
4. 4-2=2
5. 2-2=0

However, if you repeat the same process using zero, it doesn’t make sense to the calculator and it becomes an infinite loop:

1. 20-0=20
2. 20-0=20
3. 20-0=20
4. 20-0=20
5. 20-0=20
6. 20-0=20 and so on….

The same happens when a division-by-zero command is given to Facit ESA-01. This vintage machine tries perform the subtraction over and over to calculate the results.

# Don’t Be a Self XSS Victim – Facebook

How does a Self-XSS scam work?
A Self-XSS scam usually works by promising to help you hack somebody else’s account. Instead of giving you access to someone else’s account, the scammer tricks you into running malicious code that gives them the ability to use your account for fraud, spam and tricking more people into the scam.

To avoid Self-XSS attacks, never copy and paste suspicious links. Learn how to recognize a Self-XSS scam.
In many cases, Self-XSS scams emerge when someone tags you in a post claiming you can “hack any Facebook account.” That person is usually a friend who’s fallen for a similar scam previously, and a scammer is now using their account to trick more people.

An example of a Self-XSS scam asking you to paste malicious code.
The scammer will want you to follow the instructions to copy and paste the malicious code in your JavaScript console. JavaScript is a programming language used on most websites. The console lets developers test new features and change the content of pages. Most people will probably never need to use their browser’s console so if you’re asked to do so, it may be a scam.

### how do i deal with it?

If you clicked on something that turned out to be spam or your account is creating unwanted posts, events, groups or Pages, try these steps:

Review account activity and remove any spam

• Scan your computer using one of the free anti-virus scanners provided by our partners

Report spam to us

• If you come across any more spam on Facebook, report it to us. By doing so, you will be playing an important role in helping us protect other people from scams.

# Einstein and questioning

#### Exploring the inquiring mind of one of our greatest thinkers.

Let’s start with this one: “The important thing is not to stop questioning.” This is actually the first part of a longer quote, which ends with the wonderful line: “Never lose a holy curiosity.”

Einstein thought questioning and curiosity were the key to learning. In my book, I address the matter of encouraging students to question and explore in school (as opposed to just throwing “knowledge” at them and requiring them to memorize it). Einstein was keenly aware of this problem many years ago, when he said, “It is a miracle that curiosity survives formal education.” He also said, “I never teach my pupils. I only attempt to provide the conditions in which they can learn.”

Then there is my own favorite quote from Einstein:

“If I had an hour to solve a problem and my life depended on the solution, I would spend the first 55 minutes determining the proper question to ask… for once I know the proper question, I could solve the problem in less than five minutes.”

By the way, I’ve seen this quote worded in various ways. Sometimes it has Einstein saying that he’d spend “55 minutes thinking about the problem, and 5 minutes thinking about solutions.” Hopefully I can track down the original quote and its exact wording, but either way, it makes the same point (because in this case, “question” and “problem” are almost interchangeable terms). The point is, you’ve got to figure out the crux of the matter—the essential problem or question to be addressed—before focusing in on answers.

One more bit of Einstein/questioning lore: From my understanding, Einstein’s theory of relativity began with an early “beautiful question” he posed, along the lines of “What if I rode a beam of light across the universe?” and then set out to answer.
