I know of no serious scientists who doubt the age of the universe (plus
or minus a few billion).
This is not based on one single proof but myriads. I doubt if one could
open any edition of scientific american or discover magazine that does
not imply an earth or universe of much more than 6000 years. So I don't
take R. Gottlieb very seriously

Let's start with premises.  Here's mine:
The Ikkar TSBP is the Beis Din Hagadol in the Lishkah - See Rambam Hil.
Mamrim 1:1

It follows, that - exluding takkanos, gzeiros and minhaggim - that
the ikkar TSBP after the Churban is that TSBP that bests approximates
the original.

The earlier the Dor, the more Torah from the last Sanhedrin is
rememembered. The later the Dor the more that is forgotten.
Niskatnu - at least in terms of Halachic prciess is primarioly a
function of collective memory DYSfuction, and not so much a lower level
of tzidkuss, although there is something to be argued for the tzidukuss
definition, too.

Lemashal The GRA could be considered a Rishon because he could restore
and revive a lot of forgotten Torah via his methods.

It seems that early amoraim were unaware or clueless that there was any
problem with disgreeing with a Tannaim, Notice a lot of tiyvtas on Rabbi
Yochana because he paskened in contradition to braissos. He probably
was niftar long before he knew that this was a problem. The voice of
the Gmara - aka the so-called Stam - takes this for granted. But it
is not so obvious that Rav, Shmuel or R. Yochanan {etc.} were aware
that an era had ended. This is apparently a retrofit from later on.
I'm not sure which generation to be sure...

See Arvei Psachim were Shmuel paskens neither like R. Yehuda nor like R.
Yossi, and the Rashhbam. Tosafos, Yerushalmi etc.

Maybe the problem with arguing is only with the consensus of a generation.
IOW, once the Tannaitic issue was settled, then it the matter was frozen.
Same with the Gmara. once the Gmara was closed - AND a clear psak given
- the issue was closed. The same might be said for Rishonim - when the
matter had a clear psak. And Beis Yosef and Rema did their best to come
to a conclusion based upon the Torah of the Rishonim. Note that neither of
them - AFAIK - ever went bakc to the Gmara itself to prove their points.
Rather they weighed the voices of Rishonim etc.

R. Elyashiv on Pesach - chumrot


There have been no comments on what I viewed as his greatest chumrah
that ashkenazi women married to sefardim have to keep the gerzerah on
kitnitot because that generation accepted it on them for all generations.

I have no idea which generation accepted such a gezerah. At most other
poskin require a hatarat nedarim. Most poskim say the woman automatically
go after the customs of the wife. I don't see how a normal household
could run with the husband eating kitniyot and the wife who prepares it
does not.

BTW the shiur of R. Elyashiv for matzah is 21 grams le-chumra and 15
grams le-kula. One can combine these and eat one "large" kezayit instead
of 2 kezayits. Hence, 21 garms is actually enough for the 2 kezayit's.

I just re-read Kol dodi hagadah and he is MUCH more machmir He requires
0.7 ounces for 1 kezayiy (reasonable) but 1.5 ounces for 2 (sorry his
math is not very good). This amounts to over 40grams or more than twice
R. Elyashiv's most chumra shitah. He also mentions that the shiur for
maror goes up with each edition (good thing mine is a few years old).

That fits my recollection. But that doesn't fit the chemistry -- in
practice libun kal would be sufficient to reduce any biochemical to ash
(and therefore make it mutar). Nor does it get to the underlying issue:
that that which is bal'uah must be less than 1:60 of the material in the
pot. We aren't treating the ta'am balu'ah within the pot in a chemist's
manner.

Over Shabbos, my son picked up a pamphlet called Hidurei HaMidos written
by R. Hadar Margolin (who was my son's 11th grade Rebbe in Ma'arava). I
only read part of the second half of it. In the second half, he attempts
to disprove R. Chaim Naeh's shitta in reviis by showing that RCN's
shiur was based upon a mistake in the weight of the derham, the coin
which the Rambam cites in explaining midos. (The Rambam says that the
a reviis weighs approximately 27 derhams) The mistake was that RCN said
the derham weighed 3.2 grams. AIUI, today, hundreds of derhams have been
found, with an average weight of 2.8 grams and none over 3.04 grams (as
described in numismatic catalogues). I have not yet read the first half,
where he attempts to disprove the Chazon Ish's shita, but he says there
that the CI held that the derham weighed 5.5 grams.

He claims that a reviis should be 75ml (2.5 oz.) as compared with 2.86
oz. for RCN and 5 oz. for the CI. Towards the end, he brings b'derech
agav that a k'beitza should be 50 cubic centimeters as is today's egg
(!!!) and that you can calculate a k'zayis from that (I recall hearing
from R. Yitzchak Mordechai Rubin in 5755 that a k'zayis of matza is the
amount that would fit into an Israeli matchbox if you grind it up).

The pamphlet is meant to be a teaser for a full sefer to be published
later this year. It has one haskama - from R. Ezriel Auerbach, which
basically says "this is very interesting, but we have to keep to our
masores."

But how do you measure the kezayis? You're not going to crunch up the
matzah you're about to eat. And even if you were, how small do you crunch
it? Different sizes would allow different dough-air ratios. And should
the ideal be zero air? Whole matzah has bubbles too. Nor can you drop it
in water to see the volume it displaces.

So, it has become common to use estimates based on the area of the matzah
eaten. This estimate relies on all matzos having roughly the same thickness,
and therefore a reliable conversion from area to volume. Which makes for an
unreliable estimate.

Matzos (assuming all are the crispy kind) have roughly the same weight
per volume. While still imperfect, it's far more consistant than any
other measuring system at our disposal.

Doing the translation by printing the weight of a kezayis of matzah is
our most accurate way of relaying the proper amount to eat.

This is what I had in mind as well. But this morning, I received a
response off list from Rav Teitz that in order for this to work, you
would have to drink the reviis off the top of your cup, and then pour
it into a separate cup for the 'seuda' part.

It is well known that the Dram RCN used was the Turkish Dram and that
in the days of Rambam was smaller and so even RCN was machmir.

According to archaelogy the eggs have not changed in size of 2000 years
until about 50 years ago. In fact todays eggs are LARGER than in old
days because of new feeding techniques.

My wife feels that Israeli eggs are larger than those in the US but this
is a private observation not based on any statistics.

according to most ashkenazi poskim that is indeed true. In the dvar
torah from the Gush there is a detailed analysis of this. Khaf haChaim
disagrees but it is not clear on what basis. As aa result many sefadim
have a larger shiur for matzah even though they accept RCN.

In fact R. Elyashiv brings for matzah the shiur of the size of a hand
with the fingers not completely open
