Some maths calculations resulting in visual similarity

Sometimes maths can be real fun in terms of how some simple calculations can result in some visually interesting results. Take a look at some of the equations below, and you can't help but admire the way that these work out

Multiplication and addition with increasing numbers
0 x 9 + 0 = 0
1 x 9 + 1 = 10
12 x 9 + 2 = 110
123 x 9 + 3 = 1110
1234 x 9 + 4 = 11110
12345 x 9 + 5 = 111110
123456 x 9 + 6 = 1111110
1234567 x 9 + 7 = 11111110
12345678 x 9 + 8 = 111111110
123456789 x 9 + 9 = 1111111110

Multiplications with similar increasing numbers
1 x 1 = 1
11 x 11 = 121
111 x 111 = 12321
1111 x 1111 = 1234321
11111 x 11111 = 123454321
111111 x 111111 = 12345654321
1111111 x 1111111 = 1234567654321
11111111 x 11111111 = 123456787654321
111111111 x 111111111 = 12345678987654321

Another Magic of Math

1 x 8 + 1 = 9
12 x 8 + 2 = 98
123 x 8 + 3 = 987
1234 x 8 + 4 = 9876
12345 x 8 + 5 = 98765
123456 x 8 + 6 = 987654
1234567 x 8 + 7 = 9876543
12345678 x 8 + 8 = 98765432
123456789 x 8 + 9 = 987654321

Then... Check this out ...

1 x 18 + 1 = 19
12 x 18 + 2 = 218
123 x 18 + 3 = 2217
1234 x 18 + 4 = 22216
12345 x 18 + 5 = 222215
123456 x 18 + 6 = 2222214
1234567 x 18 + 7 = 22222213
12345678 x 18 + 8 = 222222212
123456789 x 18 + 9 = 2222222211

Linking the space shuttle to Roman horses

Here is a pointer to how important tradition is to our current life. If somebody tells you that things are under your control, you should throw this story at them. You would think something as simple as why train tracks are a certain width would be based on scientific evaluation, but here goes. Follow the argument and go back in history:

1. The wheels on the Space Shuttle are a certain distance apart, really narrow in proportion to its huge size.
2. This is so they can haul it on railroad tracks when they move it to different parts of the country.
3. The width of the railroad tracks is based on the companies who manufactured railroad cars way back in the days when the same companies were converting over from manufacturing wagons.
4. Wagon wheels had to be a certain distance apart to fit in the ruts in the road so they bumped less.
5. The width of the road is based on Roman design, the most convenient width for Roman chariots, since ancient Rome defined the basis for road-making in ancient times.
6. The width of a chariot was based on the width of 2 horses running together.
7. So basically, part of the design of the Space Shuttle is based on the width of two horses butts!

Gotcha, that would start to make sense to you.

Incredible street drawings

People paint for a variety of reasons, and some of the painters can be extremely gifted. Can you visualize somebody painting on the street in such a way that, when viewed from certain angles, it seems that a three-dimensional object is actually there on the street ? For example, you can think that blocks have been removed from a street surface, that the street is full of garbage or rubbish, or a small boat is sailing on a small water puddle on the street. Interested, well take a look:

Getting Internet Explorer functionality in FireFox

Say you are a fan of using Firefox as your browser, and really do not prefer to use Internet Explorer for your browsing purposes. Now you come across a site or a plugin that works only in Internet Explorer. What are your options: You can not go to this site, or you can launch Internet Explorer if the site is important to you.
There is actually another option that is available to you. There is a concept supported in Firefox about launching an Internet Explorer tab within Firefox, so you can actually continue using Firefox, just elect to use the Internet Explorer tab for this purpose.
Not making sense still, well the easier way is to explore for yourself. You can actually install a Firefox add-on that gives you an Internet Explorer tab. Instalt the add-on, restart Firefox and then the right-click options on a URL will have additional options for launching an Internet Explorer tab. The add-on is available here:

Google completes your seach term

A lot of us use the Google search engine when we want to search for anything on the internet. In fact, to a lot of people, Google is the default home page that they go to when they launch the internet.
So let me show you a trick from Google. When you search, there is a special type of search where you can start entering your search item and Google will use searches made by other people to try and provide you options for completing you search terms.
The first time I saw this, it was pretty incredible. So let me show it you directly:
Just go to this search term, search for anything. As an example, say you want to search for Britney Spears. Start entering B, then r, then I and see how you search term displays options for you to choose from.
Seems magical, does it not ?

Some cool eye teasers

Read out loud the text inside the triangle below

More than likely you said, "A bird in the bush," and........
if this IS what YOU said, then you failed to see that the word THE is repeated twice! Sorry, look again.

Next, let's play with some words.
What do you see?

In black you can read the word GOOD, in white the word EVIL (inside each black letter is a white letter). It's all very physiological too, because it visualize the concept that good can't exist without evil (or the absence of good is evil ).
Now, what do you see?

Eye teaser
You may not see it at first, but the white spaces read the word optical, the blue landscape reads the word illusion. Look again! Can you see why this painting is called an optical illusion?

What do you see here?

This one is quite tricky!
The word TEACH reflects as LEARN

Test Your Brain
This is really cool. The second one is amazing so please read all the way though.


Count every "
F" in the following text:




6 -- no joke.

Really, go Back and Try to find the 6 F's before you scroll down.

The reasoning behind is further down.

The brain cannot process "OF".

Incredible or what? Go back and look again!!

Anyone who counts all 6 "F's" on the first go is a genius.

Three is normal, four is quite rare.

Send this to your friends.
It will drive them crazy.!
And keep them occupied
For several minutes..!

Generating chapter numbering in word

Q. I am writing a book using Microsoft Word and would like to skip numbering on chapter-division pages but resume numbering on the following page. How do I do this?

A. In current versions of Microsoft Word, one way to adjust page numbers within a long document is to make each chapter a separate section. You can then manually adjust the page numbers within that section.

To divide the document into separate sections, click your cursor at the point where you want to create a new section, say, at the end of each chapter, and then select the Break option from the Insert menu. In the Break box, you can specify where you want the new section to begin, say, "t" to follow continuously on the same page or "n" to start on the next page.

The dialogue box for adding page numbers is found under Word's Insert menu with the Page Numbers option. This box lets you choose where you want the numbers to appear on the page and how they should look. Click into each section to adjust the page numbers for that chapter.

Uncheck the box next to "Show number on first page" in the Page Numbers box. This will remove the page number from the first page of your new chapter, which should be the chapter division page.

Next, click the Format button in the Page Numbers box. Click the "Start at" button and type in the page number you want for the start of the new chapter. Even though it won't display the number on the page, Word will count the chapter division page and display the next number on the following page. If you don't want the chapter-division pages numbered or counted, start the page sequence one number earlier in the "Start at" box.

For example, your first chapter ends on Page 25 and you want to skip the number on the chapter division page and have the first real page of the second chapter be Page 26. In the Page Numbers box for the second chapter-section, click Format and then "Start at" Page 25. Word will count the unnumbered chapter division page as Page 25 and visibly number the first page of the second chapter as Page 26.
