As we know honor of one's parents has certain limits. The way Naphtali Troup in his חידושי הגרנ''ט is simple--it is a מצוות עשה. -a positive command. Thus it does not override a negative command that has karet [being cut off from one's people] attached to it. But as people get  more and more religious this command of honor of ones parents and also most of the commands of בין אדם לחבירו [obligations between man  and his fellow man] get thrown out. This is no secret, and it it fact was one of the primary motivations of Reb Israel Salanter in creating the Musar Movement.

The Litvak Yeshiva world -thank Heavens is aware of this- and in fact tries to walk the middle path of emphasis on both sets of obligations-between man and God and between man and man. It is also tries to avoid the Intermediate Zone by simple concentration of learning Gemara.

Still in the USA, parents as such were despised. And the USA and the West was very anti-parent until the 1990's when instead the USA became anti-father. So I had both from inside and from outside the yeshiva world little motivation to follow in my fathers foot steps. If I would have, I would have learned Torah mainly on Shabat and during the gone to Cal Tech and volunteered for the USA Air Force. All in all I would have to say my father was a hard act to follow.--Besides just being a great father and husband.

Still the wisdom of Time has shown me how right he was and I have tried for some time to make up for my lack of balance. Going to school and majoring in Physics was part of that trying to make up for lost time.

[It might have been helpful if I had found a method for learning Physics which I only discovered later in the writings of the Ari {Isaac Luria} and in the Musar book אורחות צדיקים. The Ari brings the idea of saying the words forwards and backwards in his שער רוח הקודש and that certainly helped me in my few years at NYU. The other thing was what is called דרך גירסה--saying the words and going on with no concern whether I understand or not. That is from the Musar book ארחות צדיקים and that I found helpful more recently.]
