Lord Kelvin (William Thomson) didn't just tell other scientists about his proposed scale; he actively presented his work and defended it through multiple channels:

* Published papers: He published his ideas in scientific journals, most notably in the *Transactions of the Royal Society of Edinburgh* in 1848.

* Presentations and lectures: He gave lectures and presentations at scientific societies, including the Royal Society of London, where his work was received with interest and some initial skepticism.

* Correspondence: He engaged in extensive correspondence with other scientists, discussing his ideas and answering their questions.

* Debates: He participated in scientific debates, defending his absolute temperature scale against alternative proposals and criticisms.

It's important to note:

* The concept of absolute zero and an absolute temperature scale wasn't completely new. Guillaume Amontons had proposed the concept of an absolute zero in the 1700s, but his work was largely forgotten.

* Kelvin's contributions were crucial in establishing a rigorous scientific basis for the absolute temperature scale, connecting it to thermodynamic principles and making it widely accepted within the scientific community.

So, Kelvin's work wasn't just about proposing a scale, but also about building a strong scientific foundation for it and effectively communicating it to his peers.
