A question which might help to shed light on this: If very finely divided
iron dust is exposed to air, it will burst into flame. This is not a case
of carbon combustion, rather a very fast 'rusting' reaction which looks
like a carbon fire. Many chemical reactions resemble carbon combustion,
and carbon combustion can take place in ways that do not resemble fire.
The question is, what, at the fundamental level, defines the halachic
concept of 'esh'. What about initiating other chemical reactions?
Clearly initiating any chemical reaction is not asur, because just about
any activity, such as eating, would do so, But what about when the
chemical reaction appears to separate a substance into two components,
such as gas and solid, or two solids?. Similarly I believe that heating
metal until it melts is asur. Do similar principles of change of phase
apply in other situations? These are fundamental questions of the
interaction between Shabbat and science - do we have any experts here?

Re: Hot Pad selfheating footwarmer on Shabbos


This device which produces an exothermic chemical reaction providing heat
obviously isn't an issur d'oraita as there's no flame. But it could be
Nolad. See: Rambam Hilchot Shabbat 4 :6 "aval ein manichin kli she'yesh
bo davar tzonen al gabei kli cham she'harei molich bo chom b'shabbat".
I think this question was asked in the army here a few years ago by
soldiers staioned on top of the Chermon during the winter with below
zero temperatures.

Incidentally, there's a quite bizarre far infrared emitting textile
that produces temperatures over yad soledet (with no shaking or chemical
reaction involved)and I wonder what its halachic status will be. (My lab
at the medical school is actually getting 10 square yards of this in 2
weeks for testing on diabetic patients so maybe I'll "patchgeh" around
with a sq. foot. If it heats up food, then we have a serious question
how to deal with it on shabbat since it's not really "hatmanah". The
fabric is supposed to be kept 4 inches from the patient's skin.).

[The exothermic reaction generates heat; the fabric contains it
intrinsically]

Nesher


In RNSlifkin's email for this week, he pointed out that the nesher
takes Vayiqra 11:13-19 to indicate that the nesher is the paradigmatic
owf tamei.

Which makes the expression "al kanfei nesharim" interesting. Why is the
mashal that of being saved by a tamei bird?

Ad kan the serious question. Now for some idle speculation likely to
irritate RSBA and RnSBoublil alike....

Chazal and the meforshim see Kenaan's lowly and immoral act as a "binyan
av" (paradigm) for all avadim.

MR Ber. 36:5: R. Yaakov said: why is an eved [kenani] freed for an "eye"
or a "tooth" -- from here [in Beraishis by Kenaan] because its says Kenaan
"looked" and "spoke" [with his teeth about Noach's nakedness].

See R Bechaya (Ber.) and Chizkuni (to Shemos 21:5) who quote this Midrash.
Shem Mishmuel to Parshas Noach on this Midrash: sight and speech are
spiritual powers in the human being, and it is inappropriate for human
beings who have these gifts of speech and sight to be enslaved, except
when man misuses them. The pain of a lost eye or tooth cleanses the
abuse and thus the eved goes free.

Haamek Devar to Ber. 9:25 on the clause "eved avadim": 
Offspring of Shem and Yefes were also enslaved, and not all offspring
of Kenaan were. Rather the curse is that due to Kenaan's lowly act he
and his offpsring (whom Kenaan commanded to love theft, immorality
etc.) developed in themsleves a corrupt slave mentality wheras the
offpsring of Shem and Yefes "aspire to be free" (shoef leheyos chofshi)
and will therefore through their "hishtadlus" become free. "Therefore
every eved akum is called an eved kenani because it was Kenaan who was
the paradigm of this slave mentality".

I cannot resist including yet another insight from RSRH Ber. 14:14. Lot
is taken captive by the four kings and Avraham goes out to battle to
save Lot. He leads an army of 318 "chanichav yelidei baisav". He had
318 human souls whom he had enobled and educated [lashon chinuch] to
the pure human calling in the midst of general degneration. They are
yelidei baisav "born in his household" which is why they could become
"chanichav", unlike Lot who could not be enobled because he was an
already formed character. Education must begin at birth. In the next
verse these human souls of his household are called "avadav". This may
well provide an illuminating insight into "slavery" in the people of
Abraham. It was a way to win human souls over from pagan degeneracy to
Abrahamitic clarity of thought and truth. "A Jewish slave became a "ben
beris", a son of the covenant with G-d, and this relationship formed a
striking contrast to slavery of modern times where a man would risk his
life if he gave slaves spiritual and moral education."

Although it is hard for us westerners to accept the concept, we Jews see
ourselves as exchanging servitude to Pharoah with servitude to G-d [a
person is only truly free to the extent that he labours in Torah]. The
Maharal in Shemos 12:6 (this week's parsha :-) explains that the two
mitzvos of Bris Milah and Korban Pesach represent this aspect of our
relationship with G-d (see Gur Aryeh for the details). So there is much
to learn from the Torah view, even with reference to ourselves, who are
blessed with freedom, which should not at all be confused with the cruel
system of the nations.

Prof. Sperber's explanation concerning the relationship of the bird with

appears to be evidence that the bird perches on the crocodile's back,
it is not so clear if it really enters the croc's mouth:

Our bathrooms are not their bathrooms.

As recently as 100 years ago or perhaps even more recently than that,
"bathrooms" were literally outhouses. This is what is considered a
"House of the chair" or Beis HaKisei. I encountered still existing such
facilities in Meron where they did not have plumbing at one particular
facility. Trust me! there is a good reason for not allowing Teffilah
in such places. They are literally a "Graf Shel Reyee" and quite
unbearable to be in, near, and around... for those of us "spoiled"
by modern conveniences.

Our "bathrooms' with modern plumbing where the Tzoeh is literally
flushed out of the room is nowhere near comparable to anything like
an outhouse. The same thing is true of airplane bathrooms. There is no
Tzoeh left in the room after flushing. So, for all intents and purposes
our bathroomshave no din of a Beis Hakisei but Poskim feel that as a
matter of Kavod one should not use a room for Devarim Shebekedusha. It
is just a Chumra and not Ikkar HaDin, IIRC.

AFAIK (and this is what I recall Rav Nebenzahl telling my chavrusa and
me in Yeshiva since in most of the world outside of Israel they don't
put sinks outside the bathroom and the kitchen), you can wash your hands
in the bathroom, but you should not dry them completely, and then you
leave the bathroom, dry them and make the bracha (where required).

But I found RAZ's assertion puzzling for a different reason. Airplane
bathrooms have a tank beneath them to store the waste - but those tanks
also have an airtight seal (think about the sound that an airplane toilet
makes after flushing). Unless the toilet is stopped up, it is unlikely
to smell more - and probably smells less - than a household toilet.

But that's not the flight path either. The flight path is NNE (straight
up the east coast and then over the outer reaches of Nova Scotia
and Newfoundland and then across) at the beginning, and gradually it
turns ESE.

Interesting note on this subject.
Here in Melbourne I have noticed that the direction of davvening depends
which Shul you are in. Thus one has a choice of davvening in any one of
4 directions(!).

For the benefit of RZS and others who know Melbourne, here is a list
[of some that I can think of] - Adass Yisroel/Gerer shtiebel/Lakewood
Kollel/Merkaz Hatorah/YGk's 770 = West. Chabad/Mizrachi = North. Elwood =
East. Gandel-Besen = South.

I sometimes wonder if we are all davvening towards the same target...

I have now seen the same explanation by the Shaarei Efrayim [Shaar 10:36].
Also the Baal Torah Temimah in his peirushim al Tefilah.

Next question - "Chaverim Kol Yisroel". How does that fit in to this

My ShE has a peirush Shaarei Rachamim who guides us to: 'ayin Teshuva

The Otzar Hatefilos' peirush Dover Sholom explains that to qualify for

Hasgachah Pratit/K'lalit


I heard an interesting vort which got me thinking about these concepts -
just wanted to throw out an idea that others and I thought of - I'm sure
it's no chiddush but maybe someone can point me in the right direction.
The vort was about the distinction between 'kol man d'avid rachamana
l'tova avideh' and Nachum Ish-Gamzu's 'gam zu l'tova'.

The idea was that 'gam zu l'tova' represents a higher 'lishmah' version,
because it states that the event in question is itself of worth, rather
than 'l'tova avideh' ie rather than saying that even though it might
not be worthwhile in and of itself it will lead to good results.

This idea effectively demolishes any kind of defence of tragedy in
the world which relies on saying that it was for a good purpose in
the end (even to increase isurin so that the righteous might merit a
greater reward in Olam HaBa). Rather the tragedy must be of worth in
and of itself. It evokes a timeless and static picture of the world
(from HKBH's point of view) in which, perforce, each distinct event on
the space/time axis is chosen for it's individual worth. The basic idea
can easily be explained to fit either a Rambamist view of hasgacha or
a chassidic one, but the basic idea is the same.

What kind of sources are there that deal with this side of the question?

Eretz Zavas Chalav uDevash


Over Shabbos, I heard the following from the Lubliner:

Why does the Torah bedavqa choose these two things to praise EY? Aren't
there other items that could equally well be used to show its bounty?

"Hadam ne'eqar vena'asah chalav". Chalav is from a davar tamei, but it
itself is tahor.

Devash comes from the devorah, a davar tamei, and also somehow becomes
tahor. In fact, any bee limbs or flesh that falls into the devash becomes
devash and tahor.

This is the praise of EY, that it's metaheir hatemei'im.

(I'm sure many share my surprise that he assumes it's bee honey and not
date nectar.)

I can't understand what the material is from your description. Something
can't produce heat or any other energy continuously. It defies the laws
of conservation (if the heat is created) and/or thermodynamics (if the

Is the material some kind of self-consuming fuel?

   Charoses, like being a "servant of the Holy One" has a surface layer,

Sefiros according to REED


Appropos to our recent discussion:

The following list is from a late night reading of MmE I, pg 311. Please
check yourself and post corrections:
1- The 10 sefiros are how Hashem's actions look to us according to
our stance.
2- Even in nevuah one could not see His middos to their full extent.
3- In nevu'ah one sees from our perspective deep spiritual things in
physical forms.
4- Since what one comprehends from nevu'ah is from our perspective,
it is not a mashal at all. Rather, it is mamash the metzi'us as it
relates to us.

I thought it was relevent because:

a- He does not consider the sefiros to be real nivra'im.

b- It matches how I understood the Abarbanel to explain the Morah,
that Avraham's nevu'ah of seeing three mal'achim describes something
that actually happened, even if the perception wasn't sensory. (Not that
REED claims his is the Rambam's position.) He describes what I called a
"chazon" as opposed to a "chalom". It would seem REED altogether denies
the notion of a prophetic chalom.

This much is (I think) a Gemara in Bechoros 6b.

Reb Carl raised two points.

Regarding the first. I have often heard this assertion regarding drying
the hands outside the bathroom. Far be it from me to disagree with rav
Nebentzahl, but I always understood that to be an error. My understanding
was that either you can or cannot wash in a particular room. Drying them
outside would be of no avail if the room is not fit for washing.

Regarding the airplane. I was not discussing the smell or lack thereof. 
That is another issue. I am talking about the status of the room. I 
apologize for getting graphic. The gemara defines a beit kisei shel 
parsai as one in which the tzo'a immediately rolls away 4 amot. down a 
slanted hole. In a regular bathroom the tzo'a is immediately covered in 
the water. In an airplane there is no water. so the tzo'a just sits 
there until you flush. thus I am unsure if it too has the status of a 
beit kisei shel parsai with its attendant leniencies. There is no 
question it is infinitely cleaner than a traditional beit kisei, But 
that may not be enough of a halachik argument.

Why do we assume that one needs to pray "exactly" to EY rather than
in the general direction. The ancient shuls in the Galil face south,
I doubt they used any compass to be exact than that. Of course as one
gets closer to Jerusalem one needs to be more exact.

Similarly very few places in western Europe davened facing south-east
and I know very few places in Israel outside of Jerusalem that place
their aron kodesh on an exact angle to Jerusalem.
