The mathematical theory of linkages was once found beautiful, but is now comparatively unknown.
One of its highlights was what Florian Cajori (1859–1930) called the ‘beautiful discovery’ of the Peaucellier–Lipkin linkage (found independently in 1864 and 1871), a simple mechanism that transforms circular motion into linear motion (see attached image).
The importance of such a mechanism is that it can produce straight-line motion without using guide-rails and thus reducing friction. Previous linkages such as James Watt's (1736–1819) only *approximated* straight-line motion.
J.J. Sylvester, (1814–97) (who characterized his mathematical work as ‘the worship of the True & Beautiful’) admired a pump based on the linkage for ‘[i]ts elegance, and the frictionless ease with which it can be worked (beauty as usual the stamp and seal of perfection)’.
When the physicist William Thomson (later Baron Kelvin; 1824–1907) was able to work a model of the linkage, he was reluctant to hand it back, saying: ‘No! I have not had nearly enough of it — it is the most beautiful thing I have seen in my life’.

“Dit weekend halveren de temperaturen.”
Alleen als je de absolute #temperatuur in #Kelvin meet, kun je zeggen dat een temperatuur de helft is, omdat er dan ook half zo veel thermische #energie aanwezig is. Voor temperaturen in #Celsius kun je dat niet zeggen.

I’m so glad this website defaulted to giving me the weather in Kelvin, because I was just wondering how far from the cessation of all molecular motion the weather was… 🥶 😝

#Kelvin Oliveira vai revelar a decisão dele hoje no draft da #KingsLeague.
Ele fica no #G3X, vai pro #SantosFC ou vai jogar no time do Jake Paul.
Por todo o marketing envolvido, eu acho que ele vai ficar no G3X e jogar a Kings League Brazil.
O draft começa às 17h30 e vai ser transmitido na #CazeTV.

🚨 O Gaulês CONFIRMOU que EXISTEM NEGOCIAÇÕES entre Santos e G3X para uma ida do Kelvin Oliveira para o Santos.
O Neymar entrou em contato com o Kelvin, mostrando o desejo de jogar com ele no Santos.
As negociações estão acontecendo entre #Neymar, #SantosFC e #Gaulês (dono do #G3X, time do #Kelvin Oliveira na #KingsLeague) 🤯👀

Stavo vedendo che non ci sono moltissime informazioni storiche anche su alcune rivoluzioni che usiamo e useremo sempre più
Per esempio negli anni50 l'ingegnere inglese #JohnSumner progettò e costruì una delle prime #pompedicalore residenziali che si basava ovviamente sui lavori teorici di #carnot e #kelvin di quasi 100 anni prima
Sembra costruì una PDC con SCOP pari 3.42 con refrigerante l'anidrite solforosa e acqua scaldata a 55°
Pochissimi lo citano e non ha neanche una voce su #wikipedia

Heute vor 200 Jahren wurde William #Thomson geboren. Er entdeckte die nach ihm benannte Schwingkreisformel. Er ist auch als Lord #Kelvin bekannt, Die absolute Temperatur-Skala wurde nach ihm benannt.
