A number is said to be a Harshad number if it is divisible by the sum of its digit. For example, consider 156. The sum of its digits will be 1 + 5 + 6 = 12. 156 is divisible by 12. So, 156 is a Harshad number.

## Climate Change

You can have your own opinion, but you can’t have your own facts.

## Correlation for sceptics

And here’s your scientific proof for that. Next time you see a claim that there’s a strong relationship between two apparently unrelated factoids, so science!

Tyler Vigen Spurious Corelations

Interesting.

## Time to Quit

There comes a time when what seemed fun turns into a scramble to get ‘great’ content on this website before I forget why I once thought something was well worth the (small) effort to complete the task.

Covid took me close to the ‘meh’ tipping point, but..

## Still going

It’s been some time since I made a constructive effort to update the site. But it is (IMO) worth continuing … so we look forward to some amazing (??) fresh content appearing as well as some of the obvious under-populated sections being filled out.

Stay tuned.

## Spot the bargoon

For those of you (and hopefully, that’s a single-digit number) who are utterly innumerate, which offer is the best?

And whoever approved publishing this in a ‘paper’ needs help.

## Merry Christmas – whoever/wherever you all are (2022 edition)

Sometime in the past 12 months my predictive skills appear to have been rendered useless – so Nostradamus, how do you do it?

I have not become octuple vaccinated. For COVID, all I managed was five vaccinations plus one actual case of catching COVID-19 (on holiday in Europe!) – sometimes noted as equivalent to vaccination so close to octuple vaccinations. I can confidently state that ‘brain fog’ is a real thing, that COVID really sucks, and in a stunning literature moment my WOTY (face-to-face) got trounced by GOBLIN MODE [no shit!].

For all you readers out there that are not woke, here’s the poop on Goblin Mode  which caused a stir from people who felt Goblin Mode was a ridiculous suggestion, unused by billions on my planet … I agree!!

## North American Conservative …

“All propaganda must be presented in a popular form and must fix its intellectual level so as not to be above the heads of the least intellectual of those to whom it is directed. (…) The broad masses of the people are not made up of diplomats or professors of public jurisprudence nor simply of persons who are able to form reasoned judgment in given cases, but a vacillating crowd of human children who are constantly wavering between one idea and another.”

## Needs more than a diagram

While some written math problems are easier solved if you draw a diagram, some written math problems are beyond solution. Not because they are intractably difficult, but because the author is an idiot, the publisher is an idiot, the ‘education’ body that chose the idiot question by the idiot author, and the idiot teacher (using that word in it’s broadest sense), is innumerate and unable to see that the question cannot be solved with the information given. Here’s an example:

Go ahead. There is no solution to the problem as presented. If you see crap like this showing up in assignments then COMPLAIN long and hard. Ask your child’s math ‘teacher’ how to solve it with only the information given. Students aren’t born stupid but crap like that make them give up math ASAP.
