The actual career of my dad at TRW. TRW made the Vela satellites that had X ray detectors

 The actual career of my dad at TRW. TRW made the Vela satellites that had X ray detectors. That was one of my dad's specialties.  He had invented a supper sharp copy machine [called the copy-mate machine which he had a patent on and had a factory making it in Newport Beach CA.] based on x rays. Before that he invented the infrared telescope. 

So from 1965 and on he worked at TRW making the satellites that used x-rays. Then they used his expertise in infrared detection to make the the Infrared satellites of the  Defense Support Program (DSP).

Later after the launch of those satellites he worked on laser communication between satellites. That was the only time that I actually came with him to TRW to see the actual lab where he was making the laser apparatus to be used for satellite communications and links.

Then at that point the event of the KGB infiltration into TRW happened [that the movie  The Falcon and the Snowman  was based on.] So that was the end of government contracts for TRW (until the 1990's),-- and my dad quit his job there.

 Tosphot in Gitin page 4. First opinion: R. Elazar holds witnesses that see the giving of the  divorce doc. or the actual event of kidushin  alone count. עדי מסירה כרתי Then the second opinion is this is only for gitin and kidushin, not documents about money. Why? Because one can say he is obligated even though he is not, and by that become obligated. So two witnesses on a document ought to be enough to cause the document to be valid. 

What does this mean?  That a document of gitin and kidushin is valid, but  for the event to happen we need witnesses of the act. That is what it seems like at first glance. But Rav Shach askes that that ought not to be so because Rav Jeramiah says the Mishna where two gitin were mixed up and so each is given to both women one after the other-that mishna can not be like R Elazar. Rav Shach says if the gitin are valid, then why not? [ R Jeramiah means  both have signatures on them and those are definitely Lishma. What makes that mishna not like R Elazar is that those those signatures could not make the act of gitin valid because they are not witnesses of the act of divorce. The point of Rav Shach is the documents themselves are valid and all that is needed is two witnesses to see the giving of them over to the two women then why should that not be like R. Elazar? After all there is not reason the witnesses of the act need to be Lishma. So it must be the documents themselves are not valid even with valid signatures on them unless there are witnesses that see the act.] So it must be that in gitin and kidushin without witnesses seeing the actual event, the doc. itself is not valid.

[Avi Ezri Gitin perek 1. halacha 13] 

I am wondering about this because witnesses on the doc. itself in general ought to know for whom it is being written. So why not also witnesses of the actual event? [And in fact Rav Shach himself writes this idea later in Perek I halacha 23, that is that the witnesses need to know what is going on. They need to read the get and to know whom it is for.---not in exactly those words, but that is the idea.] That is I am thinking perhaps the first way of Rav Shach is the right way. That the doc is valid with signed witnesses but for gitin we need also them to see the act. That is I am saying that the עדי מסירה witnesses of the act also need to be lishma. and if so then the first way of Rav Shach is right. See Avi Ezri chapter I halacha 16 about what the witnesses need to know.

[I know I am not explaining this in detail. Maybe I will get a chance some other time. I was just writing this to jot down the basic idea of my question. In the meantime you might look at the Avi Ezri itself where Rav Shach explains his reasoning that the witnesses of the act do not need "lishma". That very assumption is what got me thinking that maybe they do! After all they need to be able to read the document.]

תוספות in גיטין page 4. First opinion: ר' אלעזר holds witnesses that see the giving of the  divorce doc. or the actual event of קידושין  alone count. עדי מסירה כרתי Then the second opinion של תוספות is this is only for גיטין and קידושין, not documents about money. Why? Because one can say he is obligated even though he is not, and by that become obligated. So two witnesses on a document ought to be enough to cause the document to be valid. What does this mean?  That a document of גיטין and קידושין is valid, but  for the event to happen we need witnesses of the act. That is what it seems like at first glance. But רב שך askes that that ought not to be so because רב Jeramiah says the Mishna where two גיטין were mixed up and so each is given to both women one after the other,  that משנה can not be like ר' אלעזר.  Then רב שך says if the גיטין are valid, then why not? [ [רב Jeramiah means  both have signatures on them and those are definitely לשמה. What makes that משנה not like ר'  Elazar is that those those signatures could not make the act of גיטין valid because they are not witnesses of the act of divorce. The point of רב שך is the documents themselves are valid and all that is needed is two witnesses to see the giving of them over to the two women, then why should that not be like ר' Elazar? After all there is no reason the witnesses of the act need to be לשמה. So it must be the documents themselves are not valid even with valid signatures on them unless there are witnesses that see the act.] ] So it must be that in גיטין and קידושין without witnesses seeing the actual event עדי מסירה, the doc. itself is not valid. אבי עזרי גיטין פרק א. הלכה י''ג. I am wondering about this because witnesses on the doc. itself in general ought to know for whom it is being written. So why not also witnesses of the actual event? That is I am thinking perhaps the first way of רב שך is the right way. That the doc is valid with signed witnesses but for גיטין we need also them to see the act.

תוספות בגיטין דף ד'. דעה ראשונה: ר' אלעזר מחזיק בעדים הרואים במתן השטר והאירוע של קידושין בלבד עושים חלות הקידושין או הגט. עדי מסירה כרתי. הדעה השנייה של תוספות היא שזה רק עבור גיטין וקידושין, ולא מסמכים על כסף. למה? הודאת בעל דבר כמאה עדים דמי, ועל ידי זה להיות חייב. אז שני עדים במסמך צריכים להספיק בכדי לגרום תוקף למסמך. מה זה אומר? שמסמך של גיטין וקידושין תקף, אך בכדי שהאירוע יקרה [חלות העניין] אנו זקוקים לעדים של המעשה. כך נראה במבט ראשון. אך רב שך שואל כי זה לא צריך להיות כך משום שרב ירמיה אומר את המשנה שבה התערבבו שני גיטין ולכן כל אחד מהם ניתן לשתי הנשים אחת אחרי השנייה, כי משנה זה לא יכול להיות כמו ר' אלעזר. ואז רב שך אומר שאם הגיטין תקפים, אז למה לא? [רב ירמיה אומר ששניהם חתימות עליהם ואלה בהחלט לשמה. מה שגורם לאותה משנה להיות לא כמו ר' אלעזר הוא שאותן חתימות לא יכלו להפוך את מעשה גיטין לתקף מכיוון שהם אינם עדים למעשה הגירושין. העניין של רב שך הוא שאם המסמכים עצמם תקפים, וכל מה שצריך הוא שני עדים כדי לראות את מסירתם לשתי הנשים, אז למה זה לא יהיה כמו ר' אלעזר? אחרי הכל, אין שום סיבה שעדי המעשה עדי מסירה צריכים להיות לשמה. אז זה חייב להיות שהמסמכים עצמם אינם תקפים אפילו עם חתימות תקפות, אלא אם כן יש עדים שרואים את המעשה] אז זה חייב להיות שבגיטין ובקידושין בלי עדים שראו את האירוע בפועל עדי מסירה, השטר עצמו אינו תקף. אבי עזרי גיטין פרק א. הלכה י''ג. אני תוהה לגבי זה מכיוון שעדים על המסמך עצמו באופן כללי צריכים לדעת למי הוא נכתב. אז מדוע לא גם עדים לאירוע בפועל? כלומר אני חושב שאולי הדרך הראשונה של רב שך היא הדרך הנכונה. שהשטר תקף עם עדים חתומים, אבל בשביל גיטין אנו זקוקים גם שהם יראו את המעשה

I doubt if my dad will ever get credit for anything. But on occasion I feel like complaining about it. Once Space X introduced Starlink satellites, its value jumped from 52 billion to an astonishing 120 billion according to the Morgan Stanley report in Sept 2018. But you will never see the name of Philip Rosten who developed laser communication between satellites from the late 1960's and early 1970's [at TRW]. That is the very system that connects the Starlink satellites one to the other.

And forget about seeing his name as the leader of one of the two teams that developed the U-2 camera.

Or the inventor of the InfraRed vision system used in night vision googles and in the USA satellites that use Infra-Red [Space-Based Infrared System (SBIRS)].  

[The family name was Rosenblum, but he decided to change it because he was a captain in the USAF and after the war he had to interrogate Germans and sign their release papers. The trouble of signing Rosenblum hundreds of thousands of times, made him decide to shorten his name once he would get a chance.]

Transgender.

Transgender.   If a male wants to became a female the process should be simple. Just take every single cell in his body and turn the Y chromosome into an X chromosome. On the other hand, if doctors can not do that, then they can not make him into a female by simply castrating him. [Females have two X's and males have a X and Y.]

I am on the side of Leonard Nelson in terms of non intuitive immediate knowledge

Though I am on the side of Leonard Nelson in terms of non intuitive immediate knowledge as explained in the web site of Kelley Ross.  I  think the criticism on Hegel is a bit over done. If one notices the atrocities of communism, then the best thing would be to attack Marx. Why make Hegel take the blame? 

On the other hand you might ask why do I not mention this to Kantians? Kelley Ross. Robert Hanna. Or other extremely smart philosophers nowadays? Well to be frank the fact is they are in fact very smart and very good at arguing their points. I do not stand the slightest chance of showing my point. Still I can not see that Hegel is as ridiculous as all that. Even Kelley Ross in his PhD thesis brings up two good points of Hegel twice. [About Being, and about the dialectic.]  If Hegel can be be abused, well so can the Bible. Or any system of thought about values. I can not imagine any system of thought that humans can not corrupt--no matter how perfect it is.

[There is another odd thing about all this. If you are in a classroom and the teacher gives a problem in algebra. You come up with one answer. But the the smartest kid in the class who never gets a math problem wrong comes up with a different answer. Would you not have second thoughts about raising your hand to offer your answer? I would. Well in our case, the smartest guys in the room were Carl Gauss [for Fries] and David Hilbert [for Leonard Nelson.] 

Kant Fries--seems to be on the side of Plato in terms of two levels of reality.  Hegel seems to be more along the lines of Plotinus Being leads up to Logos..[Or rather that any place one starts from leads up to Logos. 

psalms  77 and also 105 is the idea of speaking  and saying over the wonders of God. To me this seems like a clear statement about the importance of learning Physics. And I think you can see this in the Mishna Torah of the Rambam. In the first four chapters of Mishna Torah the Rambam goes into the Physics and Metaphysics as was understood by Aristotle and the later neo Platonic philosophers. And all that is contained in what the Rambam says there is to think and learn about the wonders of God to come to fear and love of God.

[Physics I think is clear what it entails. But Metaphysics? My impression is that means Plato, Aristotle, Plotinus, Kant, Leonard Nelson.]

The way to do this I suggest is to take a book of Mathematics and to just say the words in order from the beginning until the end with no repeats and no review until you reach the end. Then you go back to the beginning and start again  until you have finished the book  four times. In this way even a block of wood would understand Differential Calculus.
