Please excuse the poor quality of my microphone, as the wrong microphone was selected.   In research, we are all just building on the shoulders of true giants, and there are few larger giants than Leslie Lamport — the creator of LaTeX. For me, every time I open up a LaTeX document, I think of the work he did on creating LaTeX, and which makes my research work so much more productive. If I was still stuck with Microsoft Office for research, I would spend half of my time in that horrible equation editor, or in trying to integrate the references into the required format, or in formatting Header 1 and Header 2 to have a six-point spacing underneath. So, for me, the contest between LaTeX and Microsoft Word is a knock-out in the first round. And one of the great things about Leslie is that his work is strongly academic — and which provides foundations for others to build on. For this, he did a great deal on the ordering of task synchronisation, in state theory, cryptography signatures, and fault tolerance. LaTeX I really can say enough about how much LaTeX — created in 1984 — helps my work. I am writing a few books just now, and it allows me to lay out the books in the way that I want to deliver the content. There’s no need for a further mark-up, as I work on the output that the reader will see. But the true genius of LaTeX is the way that teams can work on a paper, and where there can be async to GitHub and where version control is then embedded. Clocks Many in the research community think that the quality measure of a paper is the impact factor of the journal that it is submitted to, or in the amount of maths that it contains. But, in the end, it is the impact of the paper, and how it changes thinking. For Leslie, in 1978, his paper on clocks changed our scientific world and is one of the most cited papers in computer science. Byzantine Generals Problem In 1981, Leslie B Lamport defined the Byzantine Generals Problem. And in a research world where you can have 100s of references in a paper, Leslie only used four (and which would probably not be accepted these days for having so few references). Within this paper, the generals of a Byzantine army have to agree to their battle plan, in the face of adversaries passing in order information. In the end, we aim to create a way of passing messages where if at least two out of three of the generals are honest, we will end up with the correct battle plan. The Lamport Signature Sometime soon, we perhaps need to wean ourselves of our existing public key methods and look to techniques that are more challenging for quantum computers. With the implementation of Shor’s algorithm [here] on quantum computers, we will see our RSA and Elliptic Curve methods being replaced by methods which are quantum robust. One method is the Lamport signature method and which was created by Leslie B. Lamport in 1979.
