## Matematik-tak: Kan du gange kinesisk?

Det er lidt kompliceret, når man skal gange fler-cifrede tal med hinanden, men man lærer efterhånden at finde en rigtig metode, når man har gået lidt i skole. Klassisk versus poetisk En klassisk europæisk model er denne: Hvis man skal regne 345 x 34 ud skal man først tage 3(0)x345=10350 og så 4x345=1380 og så lægge de to tal sammen: 10350+1380=11730. Kineserne griber det som man kan se i videoen noget mere poetisk an - man laver en række omhyggelige streger - tæller, skriver ned og når på magisk vis de samme resultater. Hvordan regner du gangestykker på papir ud? Ville du hellere have lært den kinesisk metode? Og er der overhovedet nogen fremtid for udregninger på papir i lommeregneren og computerens tidsalder?

Most people only think that there is one way to sleep: Go to sleep at night for 6-8 hours, wake up in the morning, stay awake for 16-18 hours and then repeat. Actually, that is called a monophasic sleep cycle , which is only 1 of 5 major sleep cycles that have been used successfully throughout history. The other 4 are considered polyphasic sleep cycles due to the multiple number of naps they require each day. How is this possible? How is this healthy? Well the most important of every sleep cycle is the Stage 4 REM (Rapid Eye Movement) sleep, which has been shown to provide the benefits of sleep to the brain above all other stages of sleep.
