Democrats defend "science," but what they really should be defending is "wissenschaft." No major social problems - from global warming to AI - can be solved without non-commercial research across multiple fields, including the social sciences and humanities. Really wish the party understood this.

As of today, the CDC has changed (reverted) their Covid guidance to make the vaccine recommended for all people over 18. In addition to being a smart public health move, this recommendation also means insurance must cover it. Read more here: www.cdc.gov/covid/hcp/va... Listen to a breakdown here:

I hate it so much. This can happen to you too. A year ago, almost everyone doubted this would happen. I had faculty at other schools telling me I was hysterical. (Irony!) Watch for the installation of right wing figureheads without an academic background. Watch for assaults on faculty governance.

If AI kills us in 10 years it will be because we spent $1 trillion on building gas fired data centres during a tipping point for the climate crisis. We should be spending at that level on the climate crisis, rather than trying to make trillionaires.

WTF is this "Entrepreneurial Mindset" nonsense and why is my college pushing faculty workshops about it
Text only:
Entrepreneurial Mindset: The key to success for undergraduate engineering students

Engineers can no longer depend on just their technical skill set to be successful. They also need an entrepreneurial mindset. An entrepreneurial mindset (EM) encompasses attitudes, habits and behaviors that shape a unique approach to problem-solving, innovation, and value creation.Text only:
For engineering students, EM amplifies the technical skills they learn, equipping them to 
* Recognize and identify opportunities.
* Assess and focus their impact.
* Pursue and create value in any context.Text only:
The 3Cs of Entrepreneurial Mindset
EM consists of three key elements: Curiosity, Connections, and Creating Value -- the 3Cs. A thorough understanding of the 3Cs helps engineering students question, adapt, and make positive change in classes, campus, communities, and the world.

I'm teaching a first-year seminar, very easy and open to all backgrounds. But I am still introducing students to new ideas and new ways of thinking about the world around them. And it's still true that the main takeaway isn't "content," but rather expanded perspective and the value of curiosity.

a snippet of a mini-comic, at top - straight line stretches from point A to B. Immediately below, same dot at A, then becomes a curving, meandering line that winds through the page and ends at a point with rays and a question mark emanating from it. Text reads: "Nothing can do this for you - for that robs you of experience and conflates answers with learning. Rather, it's all the decisions you make along the way, the mistakes, struggles, and surprises! These pathways you create - this is learning.
