Another day for ‘hurkle-durkling’ (19th-century Scots): lingering in bed long after it’s time to get up.

helping people with their tasks ★★★★★ doing my own tasks ★☆☆☆☆

I wish everyone on Earth knew how genuinely "off the charts" key planetary trends are right now, and how abnormal and critical it is. Things like atmospheric CO2 fraction, heat extremes on land and ocean, biodiversity loss and extinction rates. All alarms should be going off

scientist: this physical effect is very important… scientist: but we didn’t include it in the model… scientist: because it’s hard and we didn’t feel like it room full of other serious scientists: *nodding intently*

Sure, I could answer your email, and instantly forget about it. Or I could leave it unanswered, such that it lives in my mind exerting a slow, daily pressure, and I feel your spectral presence always beside me for countless weeks, and in a way, wouldn't you prefer that?

I give myself two deadlines for work, one for the person I want to be and one for the person I am.

Many congratulations to Dominic Duffy (Dominic Duffy) who successfully defended his PhD thesis today. The title of Dominic's thesis is "Development of Novel Semiconductor Materials and Type-II Heterostructures for Infrared Applications". Well done Dr. Duffy!

I've only now realized how wild it is that lasers work. An electron sees an incoming bit of light, goes "I like that vibe", and then releases its own bit of light with the same energy and rhythm (phase)? Stimulated emission is magic.

Carl Sagan passed away #OTD in 1996. In his final interviews he left us with two messages that are even more relevant today: one emphasizing the importance of a science literate public, the other a warning about how hard it is to extract ourselves when we’ve been conned.

"new year, new me!" the new me:

Me in Dec: I’ll do this in January actually Me now:

Many congratulations to Jamie McMillan who today successfully defended his PhD thesis "Traceable thermal imaging in harsh environments" based on his work NPL. Well done Dr. McMillan!

A proud supervisor moment seeing Chris and Dominic ⁦Dominic Duffy⁩ graduating with their PhDs. Well done Dr Fitch and Dr Duffy.

Well done to Dominic Duffy and Nye Ellis who presented their work on new semiconductor laser concepts at the U.K. Semiconductors conference in Sheffield last week. University of Glasgow UofG Electronics & Nanoscale Engineering

The national service nonsense does give me the opportunity to tweet one of my favourite recent bits of polling when Ipsos actually ran the famous "Yes Minister" questions as a randomised experiment, and showed that it worked.

Delighted to see that our work on the gain characteristics of “W”-lasers is finally out!
