From 1880 to 1885, Hermann Ebbinghaus ran a study about the memorisation of nonsense syllables, such as "WID" and "ZOF" by repeatedly testing himself after various time periods and recording the results. He plotted these results on a graph creating what is now known as the "forgetting curve".

Perhaps the most important discoveries are those which relate to the appropriate distribution of the periods of study...Acts of revision should be spaced in gradually increasing intervals, roughly intervals of one day, two days, four days, eight days, and so on.

The forgetting curve hypothesizes the decline of memory retention in time. This curve shows how information is lost over time when there is no attempt to retain it.

Murre and Dros present a successful replication of Ebbinghaus’ classic forgetting curve from 1880 based on the method of savings. The forgetting curve has indeed been replicated and that it is not completely smooth but most probably shows a jump upwards starting at the 24 hour data point.

The speed of forgetting depends on a number of factors such as the difficulty of the learned material (e.g. how meaningful it is), its representation and physiological factors such as stress and sleep. Furthermore higher original learning also reduces forgetting. The rate differs little between individuals.

Spitzer tested 1939 the effects of a type of spaced repetition with over 3600 students who were learning science facts and showed that spaced repetition was effective.

Spaced practice is a feasible and cost-effective way to improve the effectiveness and efficiency of learning, and has tremendous potential to improve educational outcomes.

Memory formation becomes more effective with longer inter-stimulus intervals between training sessions because of decreasing temporal overlap between successive, short-lived learning traces.

We never can tell how our lives may work to the account of the general good, and we are not wise enough to know if we have fulfilled our mission or not.

Well, I don't know what image people have of me.

One accurate measurement is worth a thousand expert opinions.

The real composer thinks about his work the whole time; he is not always conscious of this, but he is aware of it later when he suddenly knows what he will do.

To get answers, ask questions; but to get good answers, ask good questions.

If I'm producing, I'm not acting, and it's such a long road to get anything off the ground.

Why would anyone ever tell anything personal to a journalist?

Audience participation can often inject a dose of adrenalin into your average dial-tone literary reading, especially if a handful of audience-members are mentally unhinged, and let's face it - you can always depend on at least one crackpot at these things.

My friends are people who like building cool stuff. We always have this joke about people who want to just start companies without making something valuable. There's a lot of that in Silicon Valley.

When you as a designer design something that burdens a community with maintenance and old world technology, basically failed developed world technology, then you will crush that community way beyond bad design; you'll destroy the economics of that community, and often the community socially is broken.

My father's name is Dee, so when I was born they named me Katherine Dee and they took the K from Katherine and put it with his name, sort of to give me my dad's namesake. But it's hysterical how often it gets misspelled. I used to be like, 'No one capitalizes my D!'

In one way, I fear all Damascus is a dungeon. Or do you have to live here to appreciate that?

Ambiguity: the bastard child of creativity and cowardice.

When immigrants go into the worse neighborhood and they fix it up, they should become citizens.

The idea that everything is purposeful really changes the way you live. To think that everything that you do has a ripple effect, that every word that you speak, every action that you make affects other people and the planet.

I just need to figure out how to grow without compromising.

I like to use all of myself, and acting wasn't doing that.

The first famous winemaking consultant was the late professor Emile Peynaud, who reigned over Bordeaux throughout the 1940s, '50s, '60s and '70s.

There's some *NSYNC and Backstreet Boys on my iPod. I listen to it if it comes up on shuffle.

My mother-in-law, Nanny, spent her working years as a bookkeeper at a medical office in Columbus, Ohio. Like so many Americans, she worked hard and paid into Medicare, knowing that one day she could count on having high-quality health care when she needed it most.
