Note Taking

Students who take notes during a lecture or presentation achieve more than those who just passively listen.

Note-taking makes one's attention focused on the ideas being discussed, and also le...

Note Taking Cues

When the instructor says 'this is important' or 'note this', or gives a non-verbal cue that the content being discussed is important, it can enhance the student's note-taking. They can also listen to the cues to help them organize their lessons.

Revision of notes

Revision of notes, done right after the lecture, is a crucial step so that any missing lesson ideas can be filled using our short-term memory.

  • Hand-written notes are better than laptops as the latter can be distracting, with students checking email or playing games. It also distracts nearby students.

  • Laptop notes are inferior as they are verbatim and shallow.

  • Hand-written notes are well-thought-out, summarized and have a lot of graphic information that is missing from laptop notes.
Testing the longevity of bacteria

In 2014, scientists started a 500-year experiment to determine the longevity of bacteria.

The experiment consists of 800 glass vials containing either Chroococcidiopsis or Bacillus subtilis ...

Studying bacteria: The long-term plan

For the 500-year experiment to succeed, scientists are supposed to test the dried bacteria for viability and DNA damage every other year for the first 24 years and then every quarter-century for the next 475.

The team left a USB stick with instructions as well as a hard copy on paper. As neither is foolproof, the team asks that researchers will at each 25-year point copy the instructions, so they remain linguistically and technologically up to date.

Holmes practices mindfulness

Mindfulness means focusing on only one problem or activity at a time.

Our brain cannot do two things at once. “What we believe is multi-tasking is really the brain switchin...

Organize Your Brain Attic to remember more

The “brain attic” is Holmes’s analogy for the human mind and how we store information.  Just consuming information leads to mental clutter that gets difficult to access when you need it.

We are more likely to remember something if we connect it to a sensory experience or previous action, like writing or connecting memories to smells or sounds.

Take a brain break if you want to be more creative

Holmes plays the violin, because it takes him out of his thinking mind and places him in a purely physical state.

“Taking mental holidays can be incredibly productive for creativity", even something as simple as taking a walk in the park during your lunch break instead of eating at your desk.
