Various physics experiments and apparatus

[RoGeorge]

For the love of (history of) physics experiments, this YouTube channel is gold: https://www.youtube.com/user/xofunkox/videos

It is full of very clean experiments with vintage apparatus, but sometimes shows less known effects demonstrated with current days available objects:





The vintage apparatus are a great example of good engineering, a joy to watch for their simplicity, ingenuity and craftsmanship, all in good condition and still working:





And oscilloscopes are overrated:

Watched Applied Science recently?

Yep, that's where from I got the link for the Zeeman Effect video, and it turns out that the whole xofunkox channel is gold, IMO.

That is the Beauty my friend, of the GOOD aspects of the era we live in now, the things we now
understand as an intelligent species, and the experiments we share on the 'SOMETIMES' blessed 'Internet !!!

As in true life, we 'ignore' the boisterous & vexatious, and set our 'Filters' to stream in the friendly, and
knowledgeable.  We 'LEARN', and then we better 'ourselves' by re-SHARING that knowledge.
YOU, have just added yourself to such a friendly search for knowledge.  Sleep easy

Glad you like those. 

Seems like some of his experiments are from old journals of physics and chemistry. For example, in the description of the video "Automatischer Cartesischer Taucher,automatic Cartesian diver" is written:

...Eine schöne,physikalische Spielerei,gefunden in der "Zeitschrift für den physikalischen und chemischen Unterricht" Jahrgang XI 1898 Seite 213ff.Online ist die Zeitschrift (und viele andere Raritäten) hier zu finden:

with Google translate,

Eine beautiful, physical bauble, found in the "Journal of Physical and Chemical Education" Year XI 1898 page 213ff.Online the magazine (and many other rarities) can be found here:

A search inside archive.org for "Journal of Physical and Chemical Education" does not return any documents, but searching for "Zeitschrift für den physikalischen und chemischen Unterricht" returns lots of PDFs.

Unfortunately I don't speak German, but I guess there might be many more interesting experiments in those journals from 1800+.

Magnetostrictive effect will produce small length variations in a wire (in the tens or hundreds of nanometers range).

How do you measure nanometers with household items?



What a clever setup!

One of the wonders of our age is that these experiments, which were on the bleeding edge of science a century ago, which usually required either a rich patron or a university lab to create and support, can now be duplicated by literally thousands of people in their home shops.   The combination of resources and understanding available today is truly stunning.
