    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.
