Hacking Knowledge: 77 Ways to Learn Faster, Deeper, and Better
Published on Thursday 30th of November, 2006
If someone granted you one wish, what do you imagine you would want out of life that you haven't gotten yet? For many people, it would be self-improvement and knowledge. New knowledge is the backbone of society's progress. Great thinkers such as Leonardo da Vinci, Thomas Edison, Benjamin Franklin, Albert Einstein, and others' quests for knowledge have led society to many of the marvels we enjoy today. Your quest for knowledge doesn't have to be as Earth-changing as Einstein's, but it can be an important part of your life, leading to a new job, better pay, a new hobby, or simply knowledge for knowledge's sake — whatever is important to you as an end goal.
Life-changing knowledge does typically require advanced learning techniques. In fact, it's been said that the average adult only uses 10% of his/her brain. Imagine what we may be capable of with more advanced learning techniques. Here are 77 tips related to knowledge and learning to help you on your quest. A few are specifically for students in traditional learning institutions; the rest for self-starters, or those learning on their own. Happy learning.
Health
- Shake a leg. Lack of blood flow is a common reason for lack of concentration. If you've been sitting in one place for awhile, bounce one of your legs for a minute or two. It gets your blood flowing and sharpens both concentration and recall.
- Food for thought: Eat breakfast. A lot of people skip breakfast, but creativity is often optimal in the early morning and it helps to have some protein in you to feed your brain. A lack of protein can actually cause headaches.
- Food for thought, part 2: Eat a light lunch. Heavy lunches have a tendency to make people drowsy. While you could turn this to your advantage by taking a "thinking nap" (see #23), most people haven't learned how.
- Cognitive enhancers: Ginkgo biloba. Ginkgo biloba is a natural supplement that has been used in China and other countries for centuries and has been reputed to reverse memory loss in rats. It's also suggested by some health practitioners as a nootrope and thus a memory enhancer.
- Reduce stress + depresssion. Stress and depression may reduce the ability to recall information and thus inhibit learning. Sometimes, all you need to reduce depression is more white light and fewer refined foods.
Balance
- Sleep on it. Dr. Maxwell Maltz wrote about in his book Psycho-Cybernetics about a man who was was paid good money to come up with ideas. He would lock his office door, close the blinds, turn off the lights. He'd focus on the problem at hand, then take a short nap on a couch. When he awoke, he usually had the problem solved.
- Take a break. Change phyical or mental perspective to lighten the invisible stress that can sometimes occur when you sit in one place too long, focused on learning. Taking a 5-15 minute break every hour during study sessions is more beneficial than non-stop study. It gives your mind time to relax and absorb information. If you want to get really serious with breaks, try a 20 minute ultradian break as part of every 90 minute cycle. This includes a nap break, which is for a different purpose than #23.
- Take a hike. Changing your perspective often relieves tension, thus freeing your creative mind. Taking a short walk around the neighborhood may help.
- Change your focus. Sometimes there simply isn't enough time to take a long break. If so, change subject focus. Alternate between technical and non-technical subjects.
Perspective and Focus
- Change your focus, part 2. There are three primary ways to learn: visual, kinesthetic, and auditory. If one isn't working for you, try another.
- Do walking meditation. If you're taking a hike (#25), go one step further and learn walking meditation as a way to tap into your inner resources and your strengthen your ability to focus. Just make sure you're not walking inadvertently into traffic.
- Focus and immerse yourself. Focus on whatever you're studying. Don't try to watch TV at the same time or worry yourself about other things. Anxiety does not make for absorption of information and ideas.
- Turn out the lights. This is a way to focus, if you are not into meditating. Sit in the dark, block out extraneous influences. This is ideal for learning kinesthetically, such as guitar chord changes.
- Take a bath or shower. Both activities loosen you up, making your mind more receptive to recognizing brilliant ideas.
Recall Techniques
- Listen to music. Researchers have long shown that certain types of music are a great "key" for recalling memories. Information learned while listening to a particular song or collection can often be recalled simply by "playing" the songs mentally.
- Speedread. Some people believe that speedreading causes you to miss vital information. The fact remains that efficient speedreading results in filtering out irrelevant information. If necessary, you can always read and re-read at slower speeds. Slow reading actually hinders the ability to absorb general ideas. (Although technical subjects often requirer slower reading.) If you're reading online, you can try the free Spreeder Web-based application.
- Use acronyms and other mnemonic devices. Mnemonics are essentially tricks for remembering information. Some tricks are so effective that proper application will let you recall loads of mundane information years later.
Visual Aids
- Every picture tells a story. Draw or sketch whatever it is you are trying to achieve. Having a concrete goal in mind helps you progress towards that goal.
- Brainmap it. Need to plan something? Brain maps, or mind maps, offer a compact way to get both an overview of a project as well as easily add details. With mind maps, you can see the relationships between disparate ideas and they can also act as a receptacle for a brainstorming session.
- Learn symbolism and semiotics. Semiotics is the study of signs and symbols. Having an understanding of the symbols of a particular discipline aids in learning, and also allows you to record information more efficiently.
- Use information design. When you record information that has an inherent structure, applying information design helps convey that information more clearly. A great resource is Information Aesthetics, which gives examples of information design and links to their sources.
- Use visual learning techniques. Try gliffy for structured diagrams. Also see Inspiration.com for an explanation of webs, idea maps, concept maps, and plots.
- Map your task flow. Learning often requires gaining knowledge in a specific sequence. Organizing your thoughts on what needs to be done is a powerful way to prepare yourself to complete tasks or learn new topics.

Increase your Brain Activity with 15 Ideas
15 Extra Ways to Keep Your Brain In Shape
“If you nurture your mind, body and spirit, your time will expand. You will gain a new perspective that will allow you to accomplish much more.”
- Brian Koslow
It’s simple, your brain is at the center of everything you do, all you feel and think, and every nuance of how you relate to people. It’s both the supercomputer that runs your complex life and the tender organ that houses your soul. So it is very important to focus on keeping your brain in shape.
By regularly engaging in the right activities, you can increase your memory, improve your problem-solving skills and boost your creativity. Here are some extra tips on how to keep your brain in top nick.
1. Just stop.
“Take 20-30 minutes out of your day to think about nothing. But don’t sleep – you’ve got to meditate. Sit still, reduce sensory input, and try to focus your mind on something like a calm scene or a color (to begin with thinking about something rather than trying to think of ‘nothing’ is easier). A study at the University of Kentucky revealed that subjects who took a late-afternoon test after meditating for 30 minutes had better scores than those who napped for the same time.”
2. Hit the streets.
“Lace up your running shoes and get moving. A study from the University of Illinois, US, revealed that aerobic exercise actually increases brain volume. They put two groups through different regimens - one did aerobic training three times weekly for one hour; the other group did just stretching and toning exercise. The aerobics group had increased their brain volume and white matter, which forms the connections between neurons.”
3. Mix it up.
“Exercise has long been hailed as an aid to brain-power longevity. But to ensure you’re not leaving the gas on in your eighties, vary your workout routines now. Try changing things up on a regular basis and you’ll stimulate your brain more because you’re not using the same pathway over and over again.”

The Thief Of Fulfilment
Why does this happen?
It’s all to do with the way the subconscious perceives survival. It knows that you are in a safe position and that survival is more or less guaranteed if you carry on in the same way. As soon as you start to consider making changes to your life, your subconscious mind will play the fear card. You are leaving the comfort zone and boy-oh-boy, does it not like it! Not one little bit!
This is no joke. It happens to millions of people and this fear ruins their dreams for a better life. And here’s the danger of giving in to this fear: You can feel as though you’re stuck in a rut – kind of like life is passing you by. As the years pass, these feelings can become magnified and you can become filled with regret over opportunities you didn’t grasp.
I don’t know about you but the last feeling I want before I breathe my last is that I didn’t take advantage of opportunities because I gave in to my fears. Because let’s be honest here, we can generate excuse after excuse to save face and gain sympathetic understanding from our families and loved ones. But we can’t fool ourselves. Deep down inside, we know the truth."

Mental Heuristics
Some of these heuristics are age-old wisdom, bordering on cliche, but most are actually helpful.
If you want something done, do it yourself
Comment: Obviously true, and doing it is usually very good for your self esteem. A surprising amount of work can be done this way, and experts are not always necessary. However, there is a risk of becoming overworked if you try to do everything yourself - we all need other people after all.Never procrastinate anything you can do right now
Comment: Very powerful. There are many things that can be fixed or solved with a minimum of effort, but are often pushed aside as unimportant. Unfortunately they won't go away, and in time the feelings of guilt for not having done them will make you even less likely of fixing the problems.When you have several things you could be doing and don't know which to do: Just do any one of them!
Comments: If you cannot decide between two or more possibilities, then there is a good chance that the differences don't matter. However, most people begin to hesitate in this kind of situation (Fredkin's paradox). If you are conscious of this, you can just choose one choice randomly or according to some standard method.Always assume that you will succeed
Comments: If you don't expect to succeed in an endeavor, then you will not do your best and will not notice possible solutions, while if you feel that you will eventually succeed you will concentrate all your power at the problem. Of course, there is no point in attempting what you cannot do, a certain amount of self-knowledge is always needed.If you can't find a solution, change the rules.
Comment: Remember that there are no no-win scenarios.If you cannot do anything about something, there is no point in worrying about it.
Comment: Worrying is stressful, and in most situations doesn't accomplish anything - it just wastes energy. Instead of worrying about things, either do something about them or find ways around the problem. One useful idea is to write down your worries on slips of paper, and then put them away in a box. Regularly, once a week or so, you open the box and see what you can do about the worries that are still relevant.Do not rely on conscious decisions for speed - Just Do It
Comments: The conscious mind is surprisingly slow, conscious choices and actions are delayed for a significant time (a reflex acts within some tens of milliseconds, an unconscious reaction to external stimuli circa 100 milliseconds and a conscious choice several seconds). The duty of the conscious mind is usually to inhibit rather than start action, and if you become too conscious of what you are doing in a tense situation you will hesitate or slow down.It is a good idea to learn to rely on your non-conscious mind, since our conscious mind is slow and has very low bandwidth while the other systems in our brains have a tremendous capacity and actually do most of the real work anyway.
Don't try to explain away your actions for yourself
Comment: While we often do things we do not want to explain our real motivations for before other people (out of fear of embarrassment, anger or loss of image), it is a bad idea to try to convince oneself that the motivation was anything different from what it was. It will only reduce your self-knowledge with deliberate misinformation, and it is often valuable to understand what motivations you have (even if you dislike them or would never admit them in public).Listen to your intuition, but do not believe it unconditionally
Comments: Intuitive or emotional thinking, analogies, "gut feelings" or "flashes of inspiration" can sometimes give fantastic new insights or show problems from a new direction. Unfortunately such thinking isn't always reliable, and quite often completely wrong! Such insights should never be accepted because you admire their beauty or they are intuitive, only because they fit with reality.link

Good Listening In Class
Here are some things you should do to be a good listener in class.
Be Cognitively Ready to Listen When You Come to Class. Make sure you complete all assigned work andreadings. Review your notes from previous class sessions. Think about what you know about the topic that will be covered in class that day.
Be Emotionally Ready to Listen When You Come to Class. Your attitude is important. Make a conscious choice to find the topic useful and interesting. Be committed to learning all that you can.
Listen with a Purpose. Identify what you expect and hope to learn from the class session. Listen for these things as your teacher talks.
Listen with an Open Mind. Be receptive to what your teacher says. It is good to question what is said as long as you remain open to points of view other than your own."

How to Read Mathematics
by Shai Simonson and Fernando Gouvea
Mathematics is "a language that can neither be read nor understood without initiation". (Edward Rothstein, Emblems of Mind, Avon Books, page 15).
A reading protocol is a set of strategies that a reader must use in order to benefit fully from reading the text. Poetry calls for a different set of strategies than fiction, and fiction a different set than non-fiction. It would be ridiculous to read fiction and ask oneself what is the author's source for the assertion that the hero is blond and tanned; it would be wrong to read non-fiction and not ask such a question. This reading protocol extends to a viewing or listening protocol in art and music. Indeed, much of the introductory course material in literature, music and art is spent teaching these protocols.
Mathematics has a reading protocol all its own, and just as we learn to read literature, we should learn to read mathematics. Students need to learn how to read mathematics, in the same way they learn how to read a novel or a poem, listen to music, or view a painting.
When we read a novel we become absorbed in the plot and characters. We try to follow the various plot lines and how each affects the development of the characters. We make sure that the characters become real people to us, both those we admire and those we despise. We do not stop at every word, but imagine the words as brushstrokes in a painting. Even if we are not familiar with any particular word, we can still see the whole picture. We rarely stop to think about individual phrases and sentences. Instead, we let the novel sweep us along with its flow and carry us swiftly to the end. The experience is rewarding, relaxing and thought provoking.
Novelists frequently describe characters by involving them in well-chosen anecdotes, rather than by describing them by well-chosen adjectives. They portray one aspect, then another, then the first again in a new light and so on, as the whole picture grows and comes more and more into focus. This is the way to communicate complex thoughts that defy precise definition.
Both a mathematics article and a novel are telling a story and developing complex ideas. The greatest difference is that a math article does the job with a tiny fraction of the words and symbols of those used in a novel. Mathematical ideas are by nature precise and well defined, so that a precise description is possible in a very short space.
The beauty in a novel is in the aesthetic way it uses language to evoke emotions and present themes which defy precise definition. The beauty in a mathematics article is in the elegant efficient way it concisely describes precise ideas of great complexity.
What are the common mistakes people make in trying to read mathematics? How can these mistakes be corrected?"direct link

20 Productive Ways to Use Your Free Time
- Reading file. Clip magazine articles or print out good articles or reports for reading later, and keep them in a folder marked “Reading File”. Take this wherever you go, and any time you have a little chunk of time, you can knock off items in your Reading File. Keep a reading file on your computer (or in your bookmarks), for quick reading while at your desk (or on the road if you’ve got a laptop).
- Clear out inbox. Got a meeting in 5 minutes? Use it to get your physical or email inbox to empty. If you’ve got a lot in your inbox, you’ll have to work quickly, and you may not get everything done, but reducing your pile can be a big help. And having an empty inbox is a wonderful feeling.
- Phone calls. Keep a list of phone calls you need to make, with phone numbers, and carry it everywhere. Whether you’re at your desk or on the road, you can knock a few calls off your list in a short amount of time.
- Make money. This is my favorite productive use of free time. I have a list of articles I need to write, and when I get some spare minutes, I’ll knock off half an article real quick. If you get 5-10 chunks of free time a day, you can make a decent side income. Figure out how you can free-lance your skills, and have work lined up that you can knock out quickly — break it up into little chunks, so those chunks can be done in short bursts.

52 Proven Stress Reducers
-
Get up fifteen minutes earlier in the morning. The inevitable morning mishaps will be less stressful.
-
Prepare for the morning the evening before. Set the breakfast table, make lunches, put out the clothes you plan to wear, etc.
-
Don?t rely on your memory. Write down appointment times, when to pick up the laundry, when library books are due, etc. ("The palest ink is better than the most retentive memory." - Old Chinese Proverb)
-
Do nothing which, after being done, leads you to tell a lie.
-
Make duplicates of all keys. Bury a house key in a secret spot in the garden and carry a duplicate car key in your wallet, apart from your key ring.
-
Practice preventive maintenance. Your car, appliances, home, and relationships will be less likely to break down/fall apart "at the worst possible moment."
-
Be prepared to wait. A paperback can make a wait in a post office line almost pleasant.
-
Procrastination is stressful. Whatever you want to do tomorrow, do today; whatever you want to do today, do it now.
-
Plan ahead. Don?t let the gas tank get below one-quarter full; keep a well-stocked "emergency shelf" of home staples; don?t wait until you?re down to your last bus token or postage stamp to buy more; etc.
-
Don?t put up with something that doesn?t work right. If your alarm clock, wallet, shoe laces, windshield wipers ? whatever ? are a constant aggravation, get them fixed or get new ones.
-
Allow 15 minutes of extra time to get to appointments. Plan to arrive at an airport one hour before domestic departures.
-
Eliminate (or restrict) the amount of caffeine in your diet.
-
Always set up contingency plans, "just in case." ("If for some reason either of us is delayed, here?s what we?ll do?" kind of thing. Or, "If we get split up in the shopping center, here?s where we?ll meet.")
-
Relax your standards. The world will not end if the grass doesn?t get mowed this weekend.
-
Pollyanna-Power! For every one thing that goes wrong, there are probably 10 or 50 or 100 blessings. Count ?em!
-
Ask questions. Taking a few moments to repeat back directions, what someone expects of you, etc., can save hours. (The old "the hurrieder I go, the behinder I get, " idea.)
-
Say "No!" Saying "no" to extra projects, social activities, and invitations you know you don?t have the time or energy for takes practice, self-respect, and a belief that everyone, everyday, needs quiet time to relax and be alone.
-
Unplug your phone. Want to take a long bath, meditate, sleep, or read without interruption? Drum up the courage to temporarily disconnect. (The possibility of there being a terrible emergency in the next hour or so is almost nil.) Or use an answering machine.
-
Turn "needs" into preferences. Our basic physical needs translate into food, water, and keeping warm. Everything else is a preference. Don?t get attached to preferences.
-
Simplify, simplify, simplify?
-
Make friends with nonworriers. Nothing can get you into the habit of worrying faster than associating with chronic worrywarts.
-
Get up and stretch periodically if your job requires that you sit for extended periods.
-
Wear earplugs. If you need to find quiet at home, pop in some earplugs.
-
Get enough sleep. If necessary, use an alarm clock to remind you to go to bed.
-
Create order out of chaos. Organize your home and workspace so that you always know exactly where things are. Put things away where they belong and you won?t have to go through the stress of losing things.
-
When feeling stressed, most people tend to breathe in short, shallow breaths. When you breathe like this, stale air is not expelled, oxidation of the tissues is incomplete, and muscle tension frequently results. Check your breathing throughout the day, and before, during, and after high-pressure situations. If you find your stomach muscles are knotted and your breathing is shallow, relax all your muscles and take several deep, slow breaths. Note how, when you?re relaxed, both your abdomen and chest expand when you breathe.
-
Writing your thoughts and feelings down (in a journal, or on paper to be thrown away) can help you clarify things and can give you a renewed perspective.
-
Try the following yoga technique whenever you feel the need to relax. Inhale deeply through you nose to the count of eight. Then, with lips puckered, exhale very slowly through your mouth to the count of 16, or for as long as you can. Concentrate on the long sighing sound and feel the tension dissolve. Repeat 10 times.
-
Inoculate yourself against a feared event. Example: before speaking in public, take time to go over every part of the experience in your mind. Imagine what you?ll wear, what the audience will look like, how you will present your talk, what the questions will be and how you will answer them, etc. Visualize the experience the way you would have it be. You?ll likely find that when the time comes to make the actual presentation, it will be "old hat" and much of your anxiety will have fled.
-
When the stress of having to get a job done gets in the way of getting the job done, diversion ? a voluntary change in activity and/or environment ? may be just what you need.
-
Talk it out. Discussing your problems with a trusted friend can help clear your mind of confusion so you can concentrate on problem solving.
-
One of the most obvious ways to avoid unnecessary stress is to select an environment (work, home, leisure) which is in line with your personal needs and desires. If you hate desk jobs, don?t accept a job which requires that you sit at a desk all day. If you hate to talk politics, don?t associate with people who love to talk politics, etc.
-
Learn to live one day at a time.
-
Every day, do something you really enjoy.
-
Add an ounce of love to everything you do.
-
Take a hot bath or shower (or a cool one in summertime) to relieve tension.
-
Do something for somebody else.
-
Focus on understanding rather than on being understood; on loving rather than on being loved.
-
Do something that will improve your appearance. Looking better can help you feel better.
-
Schedule a realistic day. Avoid the tendency to schedule back-to-back appointments; allow time between appointments for a breathing spell.
-
Become more flexible. Some things are worth not doing perfectly and some issues are well to compromise upon.
-
Eliminate destructive self-talk: "I?m too old to?," "I?m too fat to?," etc.
-
Use your weekend time for a change of pace. If you work week is slow and patterned, make sure there is action and time for spontaneity built into your weekends. If your work week is fast-paced and full of people and deadlines, seek peace and solitude during your days off. Feel as if you aren?t accomplishing anything at work? Tackle a job on the weekend which you can finish to your satisfaction.
-
"Worry about the pennies and the dollars will take care of themselves." That?s another way of saying: take care of the todays as best you can and the yesterdays and the tomorrows will take care of themselves.
-
Do one thing at a time. When you are with someone, be with that person and with no one or nothing else. When you are busy with a project, concentrate on doing that project and forget about everything else you have to do.
-
Allow yourself time ? everyday ? for privacy, quiet, and introspection.
-
If an especially unpleasant task faces you, do it early in the day and get it over with; then the rest of your day will be free of anxiety.
-
Learn to delegate responsibility to capable others.
-
Don?t forget to take a lunch break. Try to get away from your desk or work area in body and mind, even if it?s just for 15 or 20 minutes.
-
Forget about counting to 10. Count to 1,000 before doing something or saying anything that could make matters worse.
-
Have a forgiving view of events and people. Accept the fact that we live in an imperfect world.
-
Have an optimistic view of the world. Believe that most people are doing the best they can.
