:Branco made this remark 3 years ago, and as far as I can tell nobody ever responded to it. To answer his question: scroll down to the bottom of that page, where it says "Copyright information", click that and you get a box saying "This material is copyrighted, and is not released". Pretty clear that is, so the *original* version of this article was definitely in violation of copyright. In the mean time many people have made additions/deletions/modifications, so the present version may no longer be in violation. But some paragraphs are still very similar. Should we go back, and change those paragraphs, or are we OK as is? 138.26.120.214 17:14, 17 February 2006 (UTC)

message: Someone added the above line as (non-existing) link. Quite useless for the time being, and in itself perhaps useless - or we should also start Einsteinian relativity, Minkowskian relativity etc... Harald88 19:17, 9 November 2005 (UTC)

message: "In 1899 and again in 1904 Lorentz added time dilation to his transformations and published what Henri Poincare in 1905 named the Lorentz transformations. [..] Larmor's and Lorentz's equations look unfamilar, but are algebraically equivalent to those presented by Poincaré and Einstein in 1905 (see Macrossan (1986))."
I remember having seen contrary statements in other overview papers. Thus it is worthwhile (and it is planned) to verify the above more carefully then by simply citing one review. 
Please only add information here below (either citation of alternative peer reviewed opinions or direct original information that is not open for interpretation). Harald88 16:09, 7 January 2006 (UTC)
thread_title:  To be verified: info entirely based on Macrossan 

message: The algebra required to get from eq. 3, Macrossan (1986) [Larmor's way of writing the Lorentz transfoamation] to eq. 1, Macrossan (1986) [Poincare's (1905) way of writing the Lorentz transformtion] can be checked by a school-student. So I guess the un-resolved issue must be the claim in Macrossan (1986) that eq. 3 in his paper is identical to the Lorentz transformations as written by Lorentz in 1904 and 1899. To help someone else check this, I offer some help: Lorentz (1904) wrote his transformations as eqs. 3, 4 and 5 of his paper. There is a factor l on the RHS, which Lorentz then sets to 1 (in 1899 Lorentz left l undetermined). The equations are then the same as eq.3 in Macrossan (1986). One has to be careful about what x on the RHS means. It is not the x that Poincare and Einstein use (i.e. coordinate of a point in moving frame refered to the rest frame). It is what Lorentz might call the true distance between two points in the moving frame (as opposed to what would be measured in the moving frame by contracted rulers). That is, in Lorentz's eqs. 4 and 5, x is the (x-vt) term in the modern form of the equations (a change of notation). E4mmacro 21:44, 8 January 2006 (UTC)

message: Who made the famous remark? Who is "he"? I guess Lorentz. If so it should say so; "This led Lorentz to the famous remark ...". Also, what is the reference and how famous is it? I didn't think this quote is very important. E4mmacro 10:16, 8 January 2006 (UTC)
replies: text: If you don't know it, it may be less famous than I thought. It's in a letter of Lorentz that is refered to in several articles that I read, but I don't have a reference handy, that must wait. Harald88 11:16, 8 January 2006 (UTC)

text: What exactly does in mean "At the end of my Latin"? What language did he write it in and who translated it into English? Maybe it is similar to the English expressions "at the end of my tether"? E4mmacro 21:55, 8 January 2006 (UTC)
replies: text:  It's a Dutch expression, it means not to know anymore what to say -- ready to give up. Interesting, I don't know that English expression! Harald88 22:23, 8 January 2006 (UTC)
replies: text: "Lost for words" is the closest English expression I can think of. E4mmacro 20:24, 2 April 2006 (UTC)

thread_title:  Famous remark? 

message: I put a ref to his successor Paul Ehrenfest back into the main text. I  put it in preciously, but it was removed soon thereafter by Ragesoss with the remark of removed irrelevant info. I strongly disagree with that rollback: it is important to point out that the great tradition in Theoretical Physics in Leiden was continued after his departure; perhaps we should even elaborate on that. 67.72.98.82 07:44, 17 February 2006 (UTC)

message: The biography @ Nobelprize.org states the following "Hendrik Antoon Lorentz was born at Arnhem, The Netherlands, on July 18, 1853, as the son of nursery-owner Gerrit Frederik Lorentz and his wife née Geertruida van Ginkel. When he was four years old, his mother died, and in 1862 his father married Luberta Hupkes." It appears that this info has been copied over and over again, as it re-appears like that all over the internet.
I have here right in front of me a photocopy of the death certificate of Geertruida van Ginkel, from the archives of the municipality of Arnhem. It reads as follows (my translation):  "Today, December 2nd of the year eighteen hundred and sixty one have appeared before us, Henri Jean Kronenberg J.D., Alderman and Official of Civil registration of the Municipality of Arnhem, Province Gelderland  Gerrit Fredrik Lorentz, thirty nine years old, occupation shopkeeper, and  Hendrik Anthonie Dambrink, fifty two years old, occupation carpenter  both residing here, who declared that on Sunday the first of this month, at one o'clock in the morning  Geertruida van Ginkel, born in Utrecht, residing here, without occupation, housewife of the first, earlier widow of Jan Jacob Jansen, daughter of the late Teunis van Ginkel and of Maria Simons, without occupation, residing in Beusichem, has died at the age of thirty five years and five months, at the Steenstraat in this municipality.  Of which we prepared this certificate, which after having been read has been signed by both persons mentioned before and by us  signed: G.F. Lorentz H.A. Dambrink H.J. Kronenberg"  (thanks to the webmaster of Genealogie van Teunis van Ginkel).
From this it appears that Hendrik was eight years old when his mother died, not four years as stated in the Nobelprize.org biography, and that his father was a shopkeeper rather than a nursery-owner. It is of course possible that Gerrit Lorentz had a retail nursery, but I have no information on that. JdH 17:31, 29 September 2006 (UTC)

message: The link that should have led to the footage of the funereal procession of Lorentz goes to a dead end in Dutch. I did find the footage on You Tube, and did try to add the link to that video: youtu.be/H2VtrJD0xJk, but the Wikipedia insisted that said links are verboten. -- Brothernight (talk) 04:07, 30 December 2011 (UTC)

message: The Dutch surname Lorentz is equal to the English surname Lawrence, in both cases the stress is on the first syllable. However, in English Lorentz is apparently pronounced with stress on the final syllable, according to Forvo (L.force, L.transformation). Do all English speakers stress the final syllable? (To me, English is foreign.) Then it might be interesting to mention this oddity in the article. Ceinturion (talk) 23:05, 24 July 2016 (UTC)
replies: text: I think so, yes.  There's no firm rule for foreign names, but often a syllable ending in a consonant cluster will attract stress where it would otherwise be unexpected.  This might be especially true for surnames beginning with L, as this can be mistaken for a sign of French origin.  There's also Laurent, which has final stress. —Soap— 22:59, 20 January 2018 (UTC)
