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.

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.

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".

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.

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

To give real service you must add something which cannot be bought or measured with money, and that is sincerity and integrity.

The pressure to compete, the fear somebody else will make the splash first, creates a frenzied environment in which a blizzard of information is presented and serious questions may not be raised.

Textbook rental is a great concept. It is just a great business model.

I've been intrigued by this question of whether we could evolve or develop a sixth sense - a sense that would give us seamless access and easy access to meta-information or information that may exist somewhere that may be relevant to help us make the right decision about whatever it is that we're coming across.

I thought a company that provides mutual-fund information could be a great business, because you could construct an effective moat by building large financial databases and customer lists and a strong brand name.

We've gotta become the Martians. I'm a Martian - I tell you to become Martians. And we've gotta go to Mars and civilize Mars and build a whole civilization on Mars and then move out, 300 years from now into the universe. And when we do that, we have a chance of living forever.

Keep your feet on the ground and keep reaching for the stars.

When gender comes down upon us male or female it comes as a restriction.

The thing about politicians in Britain is that they are out there, you can lobby them, get close to them, there are loads of ways you can protest against them, and booing is a pretty weak way of doing it.

The year of my birth, 1940, was the fulcrum of America in the twentieth century, when the nation was balanced precariously between the darkness of the Great Depression on one side and the storms of war in Europe and the Pacific on the other.

The greatest patience is humility.

An original something, dear maid, you would wish me to write; but how shall I begin? For I'm sure I have not original in me, Excepting Original Sin.

I practice yoga at home to a TV show called 'Inhale,' taught by Steve Ross. I figured that if the people on the show could stretch that deep then I could too. I ended up pulling my hip flexor. But that's how I met my husband. Paul was the physical therapist my coach called to meet with me after hours.

Money won is twice as sweet as money earned.

What I never overcame is a kind of shyness.

I'm about my characters.

I believe that I have always told the truth.

I'm not a great dancer. I know I'm not. But I know that I can move. I can throw shapes, just not in the right order.

Working with real wolves has been exhilarating. They're so amazing. They're these beautiful, brilliant animals and they're great to work with.

If you have the feeling of choice, if you feel free, you will be better off. And when I say better off I mean that if people feel they have control over their lives, they call in for fewer sick days from work. They have a lesser probability of having a heart attack or stroke. They live longer. They're happier.

If Americans knew how to deal with other people, they could bring peace to the world. Alas, they have not learned enough yet. The true American feels that he is 100 percent welcome anywhere he goes.

You need to have time to really hear God.

I can tell you who I'd like to work with as far as rock legends. Definitely Dave Grohl from the Foo Fighters. Of course Linkin Park. Actually, I already worked with Travis Barker on a couple of things. Gotta let the drummer get some. Possibly Paramore, Hayley Williams.

I didn't grow up in a traditional family, and I never had a family dinner around the table, so whenever I actually had a dinner 'plan,' it meant a lot to me; it made me feel excited and safe.
