It’s the 100th anniversary of the birth of Charles J. Haughey. What better way to mark this than by reading… in bookshops this week.

It is a profound and necessary truth that the deep things in science are not found because they are useful; they are found because it was possible to find them. - R. Oppenheimer

Investment in research infrastructure and sustainable core funding is not a luxury - it is a strategic necessity. It is an investment that grows the economy, strengthens public finances, and enables government to deliver on wider national priorities. https://t.co/ezZ283dpDa

Thank this man for digital communication, data compression (ZIP, MP3), coding theory, and cryptography. Claude Shannon’s biggest scientific contribution was the creation of information theory in his 1948 paper “A Mathematical Theory of Communication.” He defined “information”

Quantum Tunneling: Particles can pass through energy barriers they seemingly shouldn't be able to cross, a phenomenon critical in technologies like semiconductors and nuclear fusion in stars.

Ireland-US relations are moving towards major crisis. Text of yesterday's letter from 16 federal lawmakers urging the Trump administration to act against Ireland. Anyone in Ireland who thinks this is not serious or newsworthy doesn't know a lot about how the big bad world works.

Bastille Day. The sixth anniversary of the passing of my great friend, Robert Elgie. The very definition of the phrase “a gentleman and a scholar”. May he continue to sleep easy.

A sobering assessment from @TheEconomist of the UK economy: “Britain is stuck in its longest period of economic stagnation since the 1930s. The public finances do not add up. The cost of servicing debt as a share of GDP is the highest since 1987. “ #economy #uk #markets
