    1. The fact that someone is a billionaire doesn’t make them more capable of solving any of our problems. In fact, the pursuit of that amount of wealth means that they were able to ignore — and in fact directly profit off of — the exploitation and violation of rights that is required to get there.

      This is an astute observation about the destructive journey towards wealth concentration...it often leaves a trail of destruction in its wake. It would make a good subject for a book.

    1. The result is to scatter our attention and diffuse our concentration.

      Computer and phone notifications can be insidious. I've personally turned most of them off.

      I also find that reading and annotating with Hypothes.is has helped me to have more focus while reading---even despite the short turnoffs to cogitate a bit, write a bit, and then return.

    1. Using a terminus to indicate a certain outcome - in turn - allows for much stronger interfaces across nested activities and less guessing! For example, in the new endpoint gem, the not_found terminus is then wired to a special “404 track” that handles the case of “model not found”. The beautiful thing here is: there is no guessing by inspecting ctx[:model] or the like - the not_found end has only one meaning!

    1. Chess thinking provides a rich metacognitive context that leads me to believe that we should tease apart three notions that are related but often conflated – attention, flow and concentration. Attention is fundamentally grounded in perception (how we attend), flow is fundamentally grounded in experience (how we feel), and concentration is grounded in praxis (how we purposively coalesce).

    1. Antibiotics, according to strain sensitivity, were used at the following concentrations: tetracycline 2 μg/ml for Rm1021, BM7, BM299 and BM300, 4 μg/ml for LMG18864, 10 μg/ml for other Sinorhizobium strains and for E. coli; streptomycin 600 μg/ml and kanamycin 200 μg/ml were used for Rm1021; kanamycin for E. coli S17.1 was used at 40 μg/ml; gentamicin was used at 20 μg/ml for all strains
    1. That means when I record them, I need to have a large block of uninterrupted time, completely free of distractions, and I need to be well-rested, in a good mood, full of joyful energy and inspiration.
    2. Well, I have a four-year-old at home. I absolutely love being with my son all day, but there's definitely not much stillness around here, and any extra energy is either spent on getting some freelance work done, cleaning up the house, or trying to fit in a grownup movie or game before bed.

    1. to concentrate the viruses, the 1‐l aliquot was acidified with 1 mol l−1 acetic acid to pH ~3·0 and then viruses were filtered onto a 47‐mm, 0·45‐μm HA negatively charged nitrocellulose filter
    1. The 1MDS-method and the HA-method did not provide as high recovery yields of the virions as the Mg-method.

      The reason for this could be the beef extract used to elute the virions from both these membranes. The other two successful methods (Mg and Al) used H2SO4 for elution.

    1. Meanwhile at Microsoft's GitHub, employees at both companies have objected to GitHub's business with ICE, not to mention Microsoft's government contracts. Employees at Amazon have also urged the company not to sell its facial recognition technology to police and the military.

    1. I feel by far less distracted. My attention span feels more robust than it ever has. I also clocked in at 1000 consecutive days of meditation this past year so I’m not sure which can lay claim to more of these benefits, but my hunch is that getting rid of social media helped.

      No Facebook/Instagram/"social media" better concentration. I'm quite sure that this adheres to a lot of people.

    1. Thalamus: Our Thalamus is like a cook.  It takes in info from all the senses and then blends it with our autobiographical memory. Breakdown of the thalamus explains why trauma is primarily remembered not as a story with a beginning, middle, or end, but as isolated sensory imprints: images, sounds, physical sensations that are accompanied by intense emotions usually terror and helplessness. In normal circumstances, the thalamus also acts as a filter or gatekeeper. This makes it a central component of attention, concentration, and new learning—all of which are compromised by trauma. People with PTSD have their floodgates wide open. Lacking a filter, they are on constant sensory overload. In order to cope, they try to shut themselves down and develop tunnel vision and hyperfocus. If they can’t shut down naturally, they may enlist drugs or alcohol to block out the world. The tragedy is that the price of closing down includes filtering out sources of pleasure and joy as well.

    1. The stresses build up around the discontinuity or hole and that can be concentrated on the edges is the shape has a an elliptical shape. The more elongated the crack to more stress is concentrated at the edges of crack. The total stress was the same but because of the discontinuity the bonds at the edges of the crack saw too much stress and with this the geologic stresses of 100 see total stresses of 1000 in those sports which would mean the paradox we had is essentially solved. stresses at the tips of cracks will continually keep multiply and continue cracking until... no more airplane wings. The concentration is caused by the loss of the stress the crack or hole could have handled if were whole. Nature keeps propagating the cracks so while t the hole may keep getting bigger the force the stresses likely will not get more intense.

      Wednesday we will se how this works with compression

    1. In extreme cases, an entire project would stall because I couldn't carve out enough contiguous time to get through the next part of it.

      This is the hardest problem of writing and the ways it gets undermined can be so subtle. A roommate asking, "Is this your sock?" can wreck an afternoon.
