Here are some notes on the water cycle:

Hydrological (water) cycle

Precipitation & flow: “whether they are typhoons or Scotch mists, mountain torrents or field ditches or city sewers, they are simply water sinking back to base level, the sea.”

Evaporation = the act of passively presenting water to the atmosphere to be soaked up + vaporized by the sun’s energy.

Transpiration= evaporation thru plants

Vocabulary is a sticking point for many language learners. That’s because words have a certain arbitrary quality that makes them hard to memorize. There are two strategies which are very effective with this task: the keyword mnemonic, and retrieval practice. I have written about these extensively in my books Mnemonics for Study, and How to revise & practice.

I recently reported on a finding that memories are stronger when the pattern of brain activity is more closely matched on each repetition, a finding that might appear to challenge the long-standing belief that it’s better to learn in different contexts. Because these two theories are very important for effective learning and remembering, I want to talk more about this question of encoding variability, and how both theories can be true.

Some comments on the commonalities between the Suzuki approach to learning music and the Montessori approach to education.

My sons have both been in Montessori since they were three (they are now 8 and nearly 11, respectively). My elder son started learning the violin from a Suzuki teacher when he was around five, and now learns the piano (again, from a Suzuki teacher). My younger son has been learning the violin for the last two years. Over the years I have been somewhat intrigued by the number of parents who, like me, are both Montessori and Suzuki parents.

The two types of first-letter mnemonics

First-letter mnemonics are, as their name suggests, memory strategies that use the initial letters of words as aids to remembering. This can be an effective technique because initial letters are helpful retrieval cues, as anyone who has endeavored to remember something by mentally running through the letters of the alphabet can attest to.

There are two types of first-letter mnemonic:

Visual Language, a term introduced by Robert Horn, refers to "language based on tight integration of words and visual elements". The visual elements include shapes, as well as images (e.g., icons, clip art).

What does this have to do with memory? Well, partly of course, because the appropriate use of images usually makes information more memorable, but visual language has considerably more to offer than that. To appreciate what it is, Horn has examples at http://web.stanford.edu/~rhorn/

Most people find numbers — phone numbers, personal identification numbers, dates, and so on — more difficult to remember than words. That is, of course, why businesses try to get phone numbers that correspond to some relevant word. The system whereby this is possible — the linking of certain letters to the different digits on a telephone calling pad —is a kind of coding mnemonic. Basically, coding mnemonics are systems that transform numbers into words.

The other day I was sitting in the sunshine in my living room going through some journal articles I'd photocopied. I realized I needed to staple the pages together and went down to my study to get the stapler. Approaching my desk, I decided to check my email while I was there. And then, I decided to check my library account online to see whether a book I had requested had turned up. When I'd done that, I went back upstairs to my papers. Where I realized, of course, that I'd forgotten the stapler.

What is it?

Frontotemporal dementia is a disorder of the frontal lobes and includes what was known as primary progressive aphasia. Although it occurs far less often than Alzheimer's disease, among dementia sufferers younger than 65 it is estimated to occur at about the same rate. In other words, frontotemporal dementia is, unlike the most common dementias, not a disorder of age. Most sufferers become symptomatic in their 50s and 60s.
