Books I am reading / read

  1.  2025 feb 26 : Murderbot diary: fugitive telemetry, short novella, sarcastic humour, human  behavour observation 
  2. Murderbot diary: all systems red: Good sarcasm, short to read, perfect for trains.
  3. 2025 feb 22,23: The man who could see seconds: Good fast paced book. Huge stakes like nuclear war, kidnaps president, reads like a movie.
  4. Daemon: May be a little too powerful a daemon? that too made by a man who is already dead? If creator is dead, then there are no updates to the software to account for changes in the present.
  5. Dark matter: Very surprising plot. Cannot predict the plot before hand. Once you start, you understand it half way through. Its all family. Very good science fiction with strong family love. Though you can sort of tell where it is all going towards...
  6. Seveneves, one of the best I have read. its a journey from the way it starts to the point where it ends. Lost interest towards the end after the repopulation story starts. Became very sad in the scene where the weld the mine entrance shut.. Good book. Must have been shortened.
  7. Hail mary: one of the best I have read. Science fiction from ANdy weir. Highly recommend.
  8. Liftoff: Elon Musk and the Desperate Early Days That Launched SpaceX: Fun to read,. Curious about Elon musk. Now he is doing bad things for others and very good things for himself.
  9. The martian: One of the early books I read on the phone in a small screen till eyes watered. Amazing book. Read with the map of mars in an other tab so that you can follow his journey. Its worth doing. There is an other book about moon. I forgot its name. Same theme.
  10. Sapiens: A Brief History of Humankind: Listened as an MP3. Amazing insights. Asks many questions and answers himself. Surprising that he is a jew, in israel, against Israel , a professor in  a govt college and is very assertive.
