Hold That Thought

Book markers can be made of almost anything. Of course, they work best if they are flat and don't really alter the book in any way. They can be as simple as a recycled scrap of paper or as formal as a four-color printed reproduction of a beautiful design. I recently found this vintage style, cross-stitched and embroidered book marker. It made me smile and think of my mother.

The sweet message reads "When this you see, remember me." My mother loves to read and she's a fast reader, too. But for the thousands of books she's read, I have never seen her use a conventional book marker. When the time comes to mark her page, she will use whatever she finds within reach, a corner torn from a newspaper or magazine or an unused paper napkin is her usual choice.

When I saw this book marker, I had a eureka moment and had to buy it for her. Maybe my mother needs a special book marker she can keep nearby and call her own. As for the hand stitched message, the words should not refer to remembering me, the giver. They should refer to the book marker itself. Using the pretty little book marker, thoughtfully handmade for a glorious reader, is in fact what I hope she'll remember.

Brain Helper

The world's factual knowledge is now computable and accessible to you. You may not have been staying up nights worrying about comparing historical weather patterns or conjuring graphs to improve your household energy usage, but this is very cool. Different from a search engine, the computational knowledge engine draws from a huge collection of original data sources, not just other web sites. It also performs numerical calculations.

So, go ahead and try the newly launched Wolfram Alpha. Enter the names of two cities to get a comparison of the populations, the distance in miles between them and the time it takes to fly from one to the other. Enter your choice of a food, for the nutrition facts, calories, fat content and more. Did you know a poached egg only has 50 calories? Try something challenging.

The introduction by its creator, mathematician, scientist and software entrepreneur Stephen Wolfram is fun and helpful as a launching point.

Brain Spa

Brain anatomy. 16th century diagram of the anatomy of the human brain and the nerves associated with the senses of hearing, taste, sight and smell. The diagram, which is labeled in Latin, is from Magnus Hundt's Antropologium (Leipzig, 1501).

Have you been multitasking so much you feel you are losing your power of concentration? Treat yourself to a brain spa and sit in on a lecture from a great university. You don't need to take notes or prep for any exams, just find a seat, absorb the knowledge and stimulate your brain.

This week two new services, Academic Earth and YouTube EDU, have been launched to make your access to university classes even easier. There are no registration lines, no need to audit, no early classes, and no tuition fees. Try it and rejuvenate your brain!
