comment Can a Jew serve as a secular judge?
@DoubleAA Perhaps he was nitpicking on the word "can," a la יכול אתה אבל אינך רשאי .

comment How do we define the word 'עולם'?
For some possible counterexamples (I guess you can argue both ways about the p'shat translation): In D'varim (33:15 and 33:27), Rashi interprets both instances as referring to the world. In the latter instance, Onkelos could be referring to either the world or the universe (דבמימריה אתעביד עלמא). For another example, Rashi and Targum Yonasan both interpret Y'chezkel (32:2) as referring to the world.

@user4500 I'm not certain that's true from the standpoint of hilchos Shabbos.

... Also whether studying gemara on Shabbos is considered לצורך השבת even according to the Ritva.

comment Slide Rule on Shabbos/Yom Tov
@SethJ Regarding whether measuring for a generic mitzva is an uvdin d'chol problem, see Rambam (Hil. Shabbos 24:5, ומחשבין חשבונות של מצוה ומודדין מדידה של מצוה). However see Ritva, who prohibits (Shabbos 157b, ומסתברא דאפילו מדידה דמצוה לא שרינן אלא כשהיא לצורך השבת, ואע"ג דחשבינן חשבונות של מצוה וכל הנהו דפרק שואל (לעיל ק"נ א'), התם דיבור והלוך בעלמא הוא דשרי אבל לעשות מעשה משקל ומדה לית לן בה למשרי כיון דאפשר ליה לאחר השבת). I think there's reasonable basis for asking whether this applies to a slide rule.

comment Interpreting the Zohar's Prediction of the year 1840
@Yishai Perhaps it depends on what you mean by "messianic age", and how long that can last before the mashiach actually arrives.

comment Are corn chips mazonot?
Is this question about what to eat following kiddush on Shabbat (that happens to fall on Chanukah)? That's my impression from your stated desire to serve m'zonot after wine. If so, disregard @SethJ 's comment about the order of blessings.

@ray As you mentioned, much of the technology existed earlier, but it only proliferated in the 1840's. Likewise, aliya to Eretz Yisrael began to increase around then.

@ray Aren't you asking for explanations other than the industrial revolution and chassidus? And אמר רבי זירא שמע מינה אוירא דארץ ישראל מחכים (Bava Basra 158b), so this should fit the bill regarding wisdom.

@DoubleAA As I read it, both questions were included in the OP (and the former seems to be emphasized in the title).

comment Who needs a fence around their roof?
@msh210 1.) I think that "common practice follows this opinion", but I don't know for certain, and I don't know of a source off-hand that it does. 2.) The comment does not address other criteria for needing a ma'akeh.

comment If we don't cook a calf in its mothers' milk, why can we use eggs with chicken?
@DoubleAA R' Avishai David said that, as a child in cheder, his rebbe told the class that this was the source that basar b'chalav doesn't apply to poultry.

comment If we don't cook a calf in its mothers' milk, why can we use eggs with chicken?
@DoubleAA Basically, yes. But it's a machlokes rishonim. Tosafos hold that even chicken is d'oraysa (Chullin 104b, s.v. oaf u'g'vina, דילמא משום דסבר בשר עוף בחלב לאו דאורייתא ולא קיימא לן הכי). The Maharshal (Yam Shel Sh'lomo, Chullin 8:5, ואני אומר, מאחר דאמר ר"י ש"מ דבשר עוף בחלב מדאורייתא, הכי הלכתא) likewise maintains that b'sar chaya v'oaf is d'oraysa.

comment Who needs a fence around their roof?
In the opinion of the Aruch HaShulchan, slanted roofs do not require fencing since they are not suitable for regular use (CM 427:5, נראה דחיוב מעקה בגגין אינו אלא בגגין שלהן שהיו שוין ולא בשיפוע והיה להם הגג לתשמיש אבל גגין שלנו שהן משופעין וא"א להשתמש בהן אין בהן חיוב מעקה). As far as I know, common practice follows this opinion. Obviously, this does not make it okay to engage in dangerous activities on one's slanted, unfenced roof.

comment Source for pairing l'chaim with alcohol?
@CharlesKoppelman Tracing the European practice of toasting back to avoda zara provides by far the most compelling explanation of its origins. So accepting your explanation would possibly' require prohibiting the practice of l'chaims.

comment Source for pairing l'chaim with alcohol?
If true, and if toasting in general derives from an avoda zara related practice from Greek and Roman times, this may bring up a question of b'chukoseihem lo seileichu (along with the possibility that the explanations given by the rishonim in Gershon's answer are merely post-facto).
