Around the web – Highlights Week 39

A list of the articles I read this week (39) and the highlights I made for them.

 

Do You Really Need a Good Night’s Sleep to Exercise Well?

  • So when we’re talking about aerobic exercise like running or cycling, there’s anywhere from a small-to-zero difference in your performance.
  • Aerobic (like distance running) and anaerobic (like sprinting) sports: the difference after poor sleep is “marginal.” You might not even notice.
  • Repeated anaerobic efforts, like weightlifting: Increased fatigue.
  • Sports requiring strategy and concentration: You’re worse at making decisions.
  • “High vigilance” sports, including anything where you have to aim at a target: You’ll make more errors.
  • …athletes in a judo competition showed better strength and muscle power in the afternoon when they were well-rested, but their morning and afternoon performances were equivalent when they had only slept part of the night.

 

Here’s How to Decide When a Photo Should be Black and White

  • A monochrome image is one that consists of varying tones of one “color.” The images we commonly refer to as being black and white are indeed monochromatic, but this is just one of many ways to make a monochrome image.
  • What Role Does Color Play in the Photo?
    • The fact is color can sometimes be a distraction, or it can be rather meaningless. On the other hand, there are times when color is vital. A landscape photo that prominently features a rainbow is something that you would probably want to present in color, as the rainbow plays an important role in the scene and a black and white rainbow isn’t much to look at. Additionally, if your photo is marred by especially washed out colors or strong backlighting that can’t be satisfactorily fixed in post-processing, converting to black and white may be able to salvage the shot
  • Are there Prominent or Interesting Textures in the Photo?
    • We look at a subject like a lizard or a tree or a stone and we imagine what those things feel like — rough, bumpy, smooth, jagged. Images in which texture plays a central role benefit greatly from being converted to black and white, as black and white tends to emphasize texture, allowing the viewer to more easily appreciate what the subject “feels” like.
  • Is There Strong Contrast or Distinctive Light/Shadows?
    • Color contrast refers to how colors interact with each other. A high contrast image is one that exhibits a lot of black and white, with few or no mid lighting and shadows … work together to create strong contrast. Once colors are removed, what remains are tonal differences — the sort of contrast that contributes to powerful black and white images.
  • What Mood Do You Wish to Communicate?
    • Black and white photography works especially well for creating a dreary or dramatic moods. If you want to create a somber or mysterious atmosphere around a portrait subject, the right lighting combined with a black and white conversion is the way to go.

 

What Research Says Happiness Really Is

  • It is a striking fact that in every Indo-European language, without exception, going all the way back to ancient Greek, the word for happiness is a cognate with the word for luck… What does this linguistic pattern suggest? For a good many ancient peoples—and for many others long after that—happiness was not something you could control.
  • how does one actually measure happiness? The answer is remarkably simple (and imperfect): self-reporting. Usually these studies will ask questions like “How satisfied are you with your life?” and “On a daily basis, what kind of positive and negative emotions are you feeling?” There are no energy outputs to measure, or happiness midichlorians to count in your bloodstream. They simply use surveys to ask study participants if they’re happy at a specific moment in time.
  • When it comes to happiness, it can be broken down into four conceptual domains to clarify what kind of happiness is being examined. For example:
    • Well-being: “Overall my life is going well.”
    • Traits: “I am an enthusiastic and positive person.”
    • Emotions: “I feel gratitude and appreciation.”
    • Sensations: “It feels good to sit in this hot tub.”
  • Happiness is not:
    • Having all your personal needs met
    • Always feeling satisfied with life
    • Feeling pleasure all the time
    • Never feeling negative emotions
  • Specifically, getting plenty of exercise (especially with a set goal in mind), getting plenty of sleepdeveloping emotional intelligence, and buying experiences over material goods are good places to start. If you’re still not sure what you should be striving for, remember “PERMA.” Created by Dr. Martin Seligman, the founder of positive psychology, and published in his book Flourish, PERMA stands for the five key elements that comprise well-being:
    • Positive Emotion: Peace, gratitude, satisfaction, pleasure, inspiration, hope, curiosity, and love fall into this category.
    • Engagement: Losing ourselves to a task or project that provides us with a sense of “disappeared time” because we are so highly engaged.
    • Relationships: People who have meaningful, positive relationships with others are happier than those who do not.
    • Meaning: Meaning comes from serving a cause bigger than ourselves. Whether a religion or a cause that helps humanity in some way, we all need meaning in our lives.
    • Accomplishment/Achievement: To feel significant life satisfaction, we must strive to better ourselves in some way.

 

If You Can’t Come Up With a Good Idea, Brainstorm a Bad One

  • For starters, you’re exercising your design muscles a lot more than just staring at a blank screen: designing badly is better than not designing at all. On a deeper level, designing a purposefully bad mockup forces you to think critically on the same topics, but from a different perspective. If you can figure out the worst place to stick a call-to-action, for example, that will shed some light on the best place. This kind of productive distraction allows you to think about solutions without actually thinking about them.
