normally this time would be devoted to your second commercial or i'd like to use it now to tell you just a bit about the california academy of sciences the institution which produces science and action the academy is one of the oldest and most distinguished scientific organizations in the united states and we're quite proud of that fact the academy is dedicated to scientific research and public education and science public education  reforms here dr robert c miller academy director and noted marine biologist and that's a group of young people on an outing to study plant and animal life at the ocean's age later there's ions in action they share their experiences with thousands of other mysterious ways of a small crab are the magic of the distant planets maybe equally fascinating when it was found impossible to procure a planetarium projector from this ice company our academy staff proceeded to design the only major planetarium that has ever been completely constructed within the united states there we are on the roof of the planetarium building but the instruments we see i have nothing to do with the stars as a service to the united states weather bureau academy staff members keep regular records of various phases of the weather and natural history and science museums in this fine art aquarium continue the public education program and still another way for example more than a million and a half visitors come  science here a great hospital permitted us to film the administration of mr jim and i'm president ever to keep alive a baby unable to breathe later this became a part of one of the medical shows which brought him an important portion of any science and action series anderson he's been quite generous in sending us top scientists to tell the story of how science is applied to the products and services that we use every day and this ban extends from the comparatively new and dramatic synthetics industry to the old and still vitally important road business h areas of science and action as balance to include subjects appealing to every taste film that you are viewing covers only one topic in one field the broad overall scope of the entire program appeals to all interest in science and to all ages and certainly there is one thing i'd like to mention and that is the fact that the animal of the week feature provides an excellent bridge for the middle  commercial gives us a very good idea of the sort of thing that you might hear if you were sitting on one of these listening devices in a submarine and i do go into this next point which is the selection of personnel for submarine work which i know is a very very important thing and we have asked to come to they may be ready to escape from the sunken submarine if necessary the first given a series of dives from eighteen feet coming up with a long and then they come up and fifty feet and finally they come up from one hundred  submarine sailor has to be able to get along with his shipmates they have to have a very even disposition of the temperament they asked of the fairly dependable they have to be men that you can't stand under any circumstances know since the live rich man on board is in the hands of his fellow sailor of course that becomes vitally important of course there are a lot of other things that fit into this thing and we don't have time to go into right at the moment what sensory scenes only compliments now of  thirty one men certainly very unfortunate that we should have those losses but much looking to see what the submarines did on this chart we see that the tonnage for example of the submarines in the pacific warfare miscellaneous type of shipping sunk  here one of the deadliest submarines of all time the atomic powered u s s northwest's she is very much like a conventional submarine in that she has everything that a conventional some of what you've already heard about time does not permit us to tell about all of them but the submarine with tomic power plant will give us an indication of how atomic energy can be a brilliant blue eye flight black down here on the tail and yellow up in here and orange and on the tail feathers down in here beautiful bird about sixty three of these are known from various parts you know america is one of the largest of all a species very very beautiful zealous what are you going to do with the ring when you're going to keep him as a pest around he's quite a clown and we got a big kick out of him at least one of the most interesting but i think we've ever had o i have something very special to show you this is something that many as a lot of us have not seen it is that all that is left of the left hind leg of the largest animal that has ever lived on this earth is not an extinct animal it's an animal that lives today
