Just what every open-air pool on the 20th floor needs: a glass floor so you can look down. (at Gothia Towers)

Wintery train ride.

Main ingredient for today’s lunch.

As Green puts it, “Your computer is now only as secure as that database of keys held by Microsoft, which means it may be vulnerable to hackers, foreign governments, and people who can extort Microsoft employees.”

For at least two centuries, it has been standard practice in the United States to place commas and periods inside of quotation marks. This rule still holds for professionally edited prose: what you'll find in Slate, the New York Times, the Washington Post— almost any place adhering to Modern Language Association (MLA) or AP guidelines. But in copy-editor-free zones—the Web and emails, student papers, business memos—with increasing frequency, commas and periods find themselves on the outside of quotation marks, looking in. A punctuation paradigm is shifting.

This is a selective list of some short stories and novels that use more or less accurate science and can be used for teaching or reinforcing astronomy or physics concepts. I include both traditional “science-fiction” and (occasionally) more serious fiction that derives meaning or plot from astronomy or physics ideas.

Time is a crucial part of interaction design. At the end of the day, the absolute minutes and seconds users have to wait won’t really matter though. It’s about how people experience and remember them.

Let’s see what kind of design strategies we can use to alter time perception and potentially create more fluid experiences.

The pooled OR for myopia indicated a 2% reduced odds of myopia per additional hour of time spent outdoors per week, after adjustment for covariates (OR, 0.981; 95% CI, 0.973-0.990; P<0.001; I(2), 44.3%). This is equivalent to an OR of 0.87 for an additional hour of time spent outdoors each day. Three prospective cohort studies provided estimates of risk of incident myopia according to time spent outdoors, adjusted for possible confounders, although estimates could not be pooled, and the quality of studies and length of follow-up times varied. Three studies (2 prospective cohort and 1 RCT) investigated time spent outdoors and myopic progression and found increasing time spent outdoors significantly reduced myopic progression.

God jul! Bara ett halvår kvar till midsommar; låt oss hoppas att vi får lika fint väder då som i dag.

In this essay, I’m going to try to convince parents that it is possible, and may be beneficial, to teach their children to read even while they are babies or toddlers. I also have remarks for researchers throughout. First, I will explain how I taught my own little one, beginning at age 22 months, and introduce some of our methods. Then I will answer various general objections to the notion and practice of teaching tiny tots to read.
