Memory hack: Derren Brown teaches the method of loci

Do you struggle to remember your to-do list? Then this exercise is for you.

DERREN BROWN: We all think we're terrible at remembering things, we all complain we can't remember faces or remember names. We can remember faces often but we can't remember names at a party and we all think we have terrible memories. So, the reality is I think we sort of imagine maybe that some people just have amazing memories and we have images of Meryl Streep who can supposedly just photo read her script. I think these things don't really quite exist in the way we imagine that they do. All memory techniques are based on the idea of working with what the mind already does, which is forming memorable connections between bits of information so we lock them together.

So, for example, to give you a practical example, everything like everything great goes back to the Greeks. This is an ancient Greek technique it's called the Loci system and you can use this if you need to remember any long list of things. I use this at night if I need to remember stuff I've got to do the next day but I'm too tired to write them down. So, here's what you do: It sounds like a lot of work but it isn't once you get your head around it. Have a walk that you know around an area that you can create in your mind very easily, so it could be your street, it could be the walk from the subway station to your house or whatever. And all you need along that area are a few set points that you can remember without having to think about it because you know there's always a zebra crossing there, there's a post box, mailbox, I'm probably using quite English expressions here, there's a certain store, there's a bush whatever just things that you're very familiar with.

Say the first thing you've got to remember is I have to take my suit to the dry cleaners and I've got to do that tomorrow so you have to make a bizarre image of that thing. Say a suit that is so clean it's sort of gleaming bright white that you can barely look at it and you attach that to this image of the mailbox so you imagine someone has dressed up the mailbox in a gleaming white suit or is trying to stuff it in but the light is shining out of the little slot, whatever, you just make a bizarre image that links the two and then you forget about it you don't need to think about it. And then the next thing you do at the next location and the next thing you do at the next location and so on. And as long as you've made those images as bizarre and ridiculous as I'm making them sound, which is what's important, all you do the next day is you just mentally walk down that route again and you go why is there a white suit? Oh yeah I've got to take my suit in. And then the next one maybe is, you know, you had to call your mother and what is it? It's a big shrub by the side of the road so there's your mother in there waving a telephone from the shrub and there's branches and leaves caught up in her hair whatever just a silly image that you don't forget. So, they would do this, and the bigger your area of locations are, the better. I did this with the history of art I used to read a lot around the history of art and I was sick of forgetting about it so I know the city of London fairly well so I just took the route around the center of London that I know well, which would give me about 600 different locations and then starting in Greek St., for example, which is a city in London I started there with the ancient Greeks I would place these bizarre images at little locations so I could, by walking around this route, I could recreate the history of art as I knew it from the books that I had read. So, you can expand this thing or you can keep it small and manageable. So, that's a really good system for remembering lists.

If you want a couple of others that are probably a little briefer to describe, if you want to remember names at a party, and I don't particularly enjoy parties, so I always tend to do this because it gives me something to do, you find a link between the person's name and something about their appearance, what they're wearing, their face, their hair, something. So, you do have to listen that's the first thing when they say the name. Normally the very moment where someone is giving you their name you're just caught up in a whole lot of social anxiety anyways you don't even hear it so you have to listen. You find a link with something that they're wearing so if they're called Mike and they've got big black hair you think oh that's like a microphone so I can imagine like a big microphone walking around or if they've got a stripy T-shirt on you imagine a microphone with those stripes going around it. And it's the same process later on in the evening you see them, you look at the stripes and you go oh that's Mike. Oh yeah that's Mike. The hair, why am I thinking the hair is like a big microphone? Oh yes of course they're called Mike. And while the party dips and you're a bit bored you look around the room and see if you can do everyone's name and then you've got a couple of minutes to sort of try and recreate it if you can't quite remember. Oh yes of course it's the jacket. They've taken their jacket off that's why I can't do it so I'll link it with something else. And then at the end you get to go around and say goodbye to everybody by name and everyone thinks you're very charming and clever.

China's "artificial sun" sets new record for fusion power

China has reached a new record for nuclear fusion at 120 million degrees Celsius.

China wants to build a mini-star on Earth and house it in a reactor. Many teams across the globe have this same bold goal --- which would create unlimited clean energy via nuclear fusion.

But according to Chinese state media, New Atlas reports, the team at the Experimental Advanced Superconducting Tokamak (EAST) has set a new world record: temperatures of 120 million degrees Celsius for 101 seconds.

Yeah, that's hot. So what? Nuclear fusion reactions require an insane amount of heat and pressure --- a temperature environment similar to the sun, which is approximately 150 million degrees C.

If scientists can essentially build a sun on Earth, they can create endless energy by mimicking how the sun does it.

If scientists can essentially build a sun on Earth, they can create endless energy by mimicking how the sun does it. In nuclear fusion, the extreme heat and pressure create a plasma. Then, within that plasma, two or more hydrogen nuclei crash together, merge into a heavier atom, and release a ton of energy in the process.

Nuclear fusion milestones: The team at EAST built a giant metal torus (similar in shape to a giant donut) with a series of magnetic coils. The coils hold hot plasma where the reactions occur. They've reached many milestones along the way.

According to New Atlas, in 2016, the scientists at EAST could heat hydrogen plasma to roughly 50 million degrees C for 102 seconds. Two years later, they reached 100 million degrees for 10 seconds.

The temperatures are impressive, but the short reaction times, and lack of pressure are another obstacle. Fusion is simple for the sun, because stars are massive and gravity provides even pressure all over the surface. The pressure squeezes hydrogen gas in the sun's core so immensely that several nuclei combine to form one atom, releasing energy.

But on Earth, we have to supply all of the pressure to keep the reaction going, and it has to be perfectly even. It's hard to do this for any length of time, and it uses a ton of energy. So the reactions usually fizzle out in minutes or seconds.

Still, the latest record of 120 million degrees and 101 seconds is one more step toward sustaining longer and hotter reactions.

Why does this matter? No one denies that humankind needs a clean, unlimited source of energy.

We all recognize that oil and gas are limited resources. But even wind and solar power --- renewable energies --- are fundamentally limited. They are dependent upon a breezy day or a cloudless sky, which we can't always count on.

Nuclear fusion is clean, safe, and environmentally sustainable --- its fuel is a nearly limitless resource since it is simply hydrogen (which can be easily made from water).

With each new milestone, we are creeping closer and closer to a breakthrough for unlimited, clean energy.

The science of sex, love, attraction, and obsession

The symbol for love is the heart, but the brain may be more accurate.

  • How love makes us feel can only be defined on an individual basis, but what it does to the body, specifically the brain, is now less abstract thanks to science.
  • One of the problems with early-stage attraction, according to anthropologist Helen Fisher, is that it activates parts of the brain that are linked to drive, craving, obsession, and motivation, while other regions that deal with decision-making shut down.
  • Dr. Fisher, professor Ted Fischer, and psychiatrist Gail Saltz explain the different types of love, explore the neuroscience of love and attraction, and share tips for sustaining relationships that are healthy and mutually beneficial.

Golden blood: The rarest blood in the world

We explore the history of blood types and how they are classified to find out what makes the Rh-null type important to science and dangerous for those who live with it.

Surprising Science
  • Fewer than 50 people worldwide have 'golden blood' — or Rh-null.
  • Blood is considered Rh-null if it lacks all of the 61 possible antigens in the Rh system.
  • It's also very dangerous to live with this blood type, as so few people have it.

There never was a male fertility crisis

A new study suggests that reports of the impending infertility of the human male are greatly exaggerated.

Sex & Relationships
  • A new review of a famous study on declining sperm counts finds several flaws.
  • The old report makes unfounded assumptions, has faulty data, and tends toward panic.
  • The new report does not rule out that sperm counts are going down, only that this could be quite normal.
