- A report published last week by the Millennium Cohort Study, a long-term study group in Britain that has been following 19,000 children born in 2000 and 2001, found that those who watched more than three hours of television, videos or DVDs a day had a higher chance of conduct problems, emotional symptoms and relationship problems by the time they were 7 than children who did not. The study, of a sample of 11,000 children, found that children who played video games ? often age-appropriate games ? for the same amount of time did not show any signs of negative behavioral changes by the same age.
- But Dr. Small says we do know that the brain is highly sensitive to stimuli, like iPads and smartphone screens, and if people spend too much time with one technology, and less time interacting with people like parents at the dinner table, that could hinder the development of certain communications skills.
- Conversations with each other are the way children learn to have conversations with themselves, and learn how to be alone,? said Sherry Turkle, a professor of science, technology and society at the Massachusetts Institute of Technology, and author of the book ?Alone Together: Why We Expect More From Technology and Less From Each Other.? ?Learning about solitude and being alone is the bedrock of early development, and you don?t want your kids to miss out on that because you?re pacifying them with a device. If you don?t teach your children to be alone, they?ll only know how to be lonely.?

That's how I visualised the 7 x table. Job done.
There's always patterns. At least, there are for me, I see things in numbers and I see numbers in everything. It's a blessing and a curse, but it makes the times-tables a breeze.

There's always patterns. At least, there are for me, I see things in numbers and I see numbers in everything. It's a blessing and a curse, but it makes the times-tables a breeze.
The digits in that table, read as rows, show the last digits of each multiple of 7 up to 9 (after 10 it repeats). And the grid itself is simplicity itself to construct, even in your head.
It took me a while to interpret it too!
WelshmanEC2
I'll try - not easy to explain, it's just something I "see" without thinking.
Look on it as two grids, representing the multiples of 7
First grid is the first digit of each multiple
Second grid is the second
0 1 2
2 3 4
4 5 6
and
7 4 1
8 5 2
9 6 3
1 x 7 = first number in each grid = 0 & 7 = 7
2 x 7 = second number in each grid = 1 & 4 = 14
and so on.

20 Tips for More Efficient Google Searches - by Dumb Little Man
20 Tips for More Efficient Google Searches - by Dumb Little Man
- Either/or
Google normally searches for pages that contain all the words you type in the search box, but if you want pages that have one term or another (or both), use the OR operator -- or use the "|" symbol (pipe symbol) to save you a keystroke. [dumb | little | man] - Quotes
If you want to search for an exact phrase, use quotes. ["dumb little man"] will only find that exact phrase. [dumb "little man"] will find pages that contain the word dumb and the exact phrase "little man". - Not
If you don't want a term or phrase, use the "-" symbol. [-dumb little man] will return pages that contain "little" and "man" but that don't contain "dumb". - Similar terms
Use the "~" symbol to return similar terms. [~dumb little man -dumb] will get you pages that contain "funny little man" and "stupid little man" but not "dumb little man". - Wildcard
The "*" symbol is a wildcard. This is useful if you're trying to find the lyrics to a song, but can't remember the exact lyrics. [can't * me love lyrics] will return the Beatles song you're looking for. It's also useful for finding stuff only in certain domains, such as
educational information: ["dumb little man" research *.edu]. - Advanced search
If you can't remember any of these operators, you can always use Google's advanced search. - Definitions
Use the "define:" operator to get a quick definition. [define:dumb] will give you a whole host of definitions from different sources, with links. - Calculator
One of the handiest uses of Google, type in a quick calculation in the search box and get an answer. It's faster than calling up your computer's calculator in most cases. Use the +, -, *, / symbols and parentheses to do a simple equation. - Numrange
This little-known feature searches for a range of numbers. For example, ["best books 2002..2007] will return lists of best books for each of the years from 2002 to 2007 (note the two periods between the two numbers). - Site-specific
Use the "site:" operator to search only within a certain website. [site:dumblittleman.com leo] will search for the term "leo" only within this blog. - Backlinks
The "link:" operator will find pages that link to a specific URL. You can use this not only for a main URL but even to a specific page. Not all links to an URL are listed, however. - Vertical search
Instead of searching for a term across all pages on the web, search within a specialized field. Google has a number of specific searches, allowing you to search within blogs, news, books, and much more:
- Movies
Use the "movie:" operator to search for a movie title along with either a zip code or U.S. city and state to get a list of movie theaters in the area and show times. - Music
The "music:" operator returns content related to music only. - Unit converter
Use Google for a quick conversion, from yards to meters for example, or different currency: [12 meters in yards] - Types of numbers
Google algorithms can recognize patterns in numbers you enter, so you can search for:
- Telephone area codes
- Vehicle ID number (US only)
- Federal Communications Commission (FCC) equipment numbers (US only)
- UPC codes
- Federal Aviation Administration (FAA) airplane registration number (US only)
- Patent numbers (US only)
- Even stock quotes (using the stock symbol) or a weather forecast regarding the next five days
- File types
If you just want to search for .PDF files, or Word documents, or Excel spreadsheets, for example, use the "filetype:" operator. - Location of term
By default, Google searches for your term throughout a web page. But if you just want it to search certain locations, you can use operators such as "inurl:", "intitle:", "intext:", and "inanchor:". Those search for a term only within the URL, the title,
the body text, and the anchor text (the text used to describe a link). - Cached pages
Looking for a version of a page the Google stores on its own servers? This can help with outdated or update pages. Use the "cached:" operator. - Answer to life, the universe, and everything
Search for that phrase, in lower case, and Google will give you the answer.
