Concluded that “164 pounds of wood, barks, and roots arose out of water only.”]]> 2016-08-08 23:39:19 UTC https://padlet.com/kendall_klein/8zwlc8yg5eny/wish/117748632 kendall_klein https://padlet.com/kendall_klein/8zwlc8yg5eny/wish/117749186 Did an experiment with meat in jars to see if maggots spontaneously generated. Disproved the theory that maggots could be spontaneously generated from meat using a controlled experiment. ]]> 2016-08-08 23:49:09 UTC https://padlet.com/kendall_klein/8zwlc8yg5eny/wish/117749186 kendall_klein https://padlet.com/kendall_klein/8zwlc8yg5eny/wish/117749458 Did an experiment where he heated broth in a bottle. Concluded that living things could come from nonliving material. ]]> 2016-08-08 23:54:13 UTC https://padlet.com/kendall_klein/8zwlc8yg5eny/wish/117749458 kendall_klein https://padlet.com/kendall_klein/8zwlc8yg5eny/wish/117750015 Disagreed with Buffon, who said that living things contain "vital atoms" and when living things died these atoms were taken up by the soil. Boiled gravy and and then put it in phials and fused them shut. Concluded that Buffon was wrong by proving that it was "vital atoms" he was finding, but living organisms introduced from the air.]]> 2016-08-09 00:04:46 UTC https://padlet.com/kendall_klein/8zwlc8yg5eny/wish/117750015 kendall_klein https://padlet.com/kendall_klein/8zwlc8yg5eny/wish/117750744 Took a broth of nutrients and sterilized it by boiling and also heated the air above it to a high temperature. The result was that no microbes grew. Concluded that he killed all the microbes and that spontaneous generation was incorrect. ]]> 2016-08-09 00:17:37 UTC https://padlet.com/kendall_klein/8zwlc8yg5eny/wish/117750744 kendall_klein https://padlet.com/kendall_klein/8zwlc8yg5eny/wish/117751419 Thought that sexual generation was an act caused by a vital force as much as spontaneous generation. Named his subject heterogenesis. ]]> 2016-08-09 00:28:49 UTC https://padlet.com/kendall_klein/8zwlc8yg5eny/wish/117751419 kendall_klein https://padlet.com/kendall_klein/8zwlc8yg5eny/wish/117752061 Boiled meat in a flask that had a long neck that curved like that goose neck. There was no growth of bacteria for a bit. When the flask was turned so particles could fall the broth clouded. Still nothing grew in the flasks unless they were broken. Disproved the theory of spontaneous generation. ]]> 2016-08-09 00:38:56 UTC https://padlet.com/kendall_klein/8zwlc8yg5eny/wish/117752061 kendall_klein https://padlet.com/kendall_klein/8zwlc8yg5eny/wish/117899689 Hypothesized that infrared emission (colors of heat) known to scientists as the UIR bands were coming from molecules called polycyclic aromatic hydrocarbons (PAHs). Found that these structures could be found were stars are born and die. ]]> 2016-08-10 15:05:55 UTC https://padlet.com/kendall_klein/8zwlc8yg5eny/wish/117899689 kendall_klein https://padlet.com/kendall_klein/8zwlc8yg5eny/wish/118516505 Did experiments with with powerful laboratory “guns” and computer models the conditions that existed inside comets when these celestial objects hit Earth’s atmosphere at almost 25,000 miles per hour and crashed down upon the surface of Earth to see how amino acids and other things for life appeared. Research showed that these building blocks of life could've survived the comet crashes.]]> 2016-08-17 01:58:03 UTC https://padlet.com/kendall_klein/8zwlc8yg5eny/wish/118516505 kendall_klein https://padlet.com/kendall_klein/8zwlc8yg5eny/wish/118517277 Did research on liposomes and invented artificial lung surfactants. Called "Father of Liposomes."]]> 2016-08-17 02:08:55 UTC https://padlet.com/kendall_klein/8zwlc8yg5eny/wish/118517277 kendall_klein https://padlet.com/kendall_klein/8zwlc8yg5eny/wish/118517884 Had a theory that life on Earth developed through gradual chemical evolution of carbon-based molecules in a “primordial soup." Proposed that life occurred completely by accident.]]> 2016-08-17 02:15:46 UTC https://padlet.com/kendall_klein/8zwlc8yg5eny/wish/118517884 kendall_klein https://padlet.com/kendall_klein/8zwlc8yg5eny/wish/118518464 Conducted an experiment which demonstrated that several organic compounds could be formed spontaneously by simulating the conditions of Earth's early atmosphere. Designed an apparatus that held a mix of gases similar to those found in Earth's early atmosphere over some water, representing Earth's early ocean. Electrodes delivered an electric current that simulated light. Found that several amino acids formed.]]> 2016-08-17 02:21:53 UTC https://padlet.com/kendall_klein/8zwlc8yg5eny/wish/118518464 kendall_klein https://padlet.com/kendall_klein/8zwlc8yg5eny/wish/118519002 Research involves predicting environmental change.
