Key Takeaways

• The most puzzling, unexplained anomaly in all of cosmology is the Hubble tension: the difference in the measured expansion rate depending on which method is used.
• However, a second, less-publicized anomaly is also extremely puzzling: a difference in our observed motion through the Universe and how different things appear in various directions.
• We have many different methods of estimating how the Universe differs in different directions, and they’re not all consistent with one another. That’s a real, unsolved, but important problem!

Sorry, astronomers: the expanding Universe doesn’t add up.

The largest anomaly is the Hubble tension.

Two expansion rate measurement methods yield incompatible values.

The early relic method, via cosmic imperfections, yields 67 km/s/Mpc.

The distance ladder method, from individually measured objects, yields 73 km/s/Mpc.

But another cosmic imperfection anomaly is similarly puzzling.

Consider the cosmic microwave background (CMB): leftover radiation from the Big Bang.

Although mostly uniform, one direction is ~3.3 millikelvin hotter while the opposite is similarly cooler.

At lower left, the actual signal of the temperature fluctuations is shown. In the other three panels, possible modifications to the microwave sky are shown due to rotation or other forms of anisotropy. By constraining the magnitude of these signals, we can demonstrate just how isotropic (the same in all directions) and non-rotating the Universe actually is. However, indicators other than the CMB do not give consistent results with what we observe here  Credit: D. Saadeh et al., Phys. Rev. Lett., 2016)

The next 12 months will be another test of leadership for Canada’s CEOs.

Already in the past two years, they have dealt with the pandemic, supply-chain issues, talent shortages, technological advances, market volatility, the war in Ukraine, surging inflation and interest rates, digital transformation, and intensifying sustainability agendas. All remain ongoing concerns that tests their organization’s resiliency and agility.

Now just as the economy has started its post-pandemic recovery, a recession looms.

Ninety-two percent of the 75 top Canadian company CEOs in KPMG’s annual bellwether Global CEO Outlook Report believe the country will fall into a recession in the next 12 months.

In separate, new research, into 503 small and medium-sized businesses (SMBs), two-thirds (66 percent) also anticipate a recession. However, the majority of leaders (69 percent of CEOs and 52 percent of SMBs), irrespective of company size, are optimistic that it will be mild and short and have already taken steps to help ride out the upcoming turbulence.

While the economy and an anticipated recession are currently keeping CEOs up at night, our surveys also reveal shared concerns with global peers that emerging or disruptive technology and operational issues are forever changing the way they do business and present an ongoing threat — and opportunity — to their ability to grow.

1. Boarding Fantasy: Endless Waters And A White Ship

In your imagination, boarding a cruise ship should mean enjoying endless waters, a blue sky, and the soft breeze off the sea. You might picture yourself giggling with a few close friends while boarding a luxurious white ship, just like in the movies. However, that scenario is unfortunately not all that common on a cruise. (see Picture below)

2. Boarding Reality: Where Did All These People Come From

Since cruise ships make money by accommodating as many passengers as possible, the usual scenario when you board is often that you find yourself shoulder to shoulder with people from all walks of life and with all the noises and smells that come with them. (see Picture below)

Do you remember what it was like to be a kid? So much of the day was directed by adults. Wake up. Get dressed. Brush your teeth. Eat your breakfast. Get in the car. Go to school.

Sometimes kids listen to the instructions — and sometimes they don’t. And when they don’t, that can be very frustrating for parents.

So how can parents get their kids to be more apt to comply? It might sound counterintuitive, but one strategy widely recommended by children’s health professionals is to engage your child in short, daily sessions of child-led play.

Called “special time,” it gives young children a chance to interact with their parents without the stress of having to follow directions — which in turn, strengthens the bond between them, says Roger Harrison, a pediatric psychologist with Nemours Children’s Health in Wilmington, Del.

“Special time increases opportunities for closeness between a parent and child. As that attachment is building, it increases the likelihood that a child is going to listen or value what a parent has to say,” he says.

One of the most divisive topics in education is gifted education. Even the word itself—gifted—has caused debate. The efficacy and equity of gifted programs came under fire in 2021 when New York City mayor Bill De Blasio rolled out a plan to phase out the city’s gifted program completely—a plan that was later quietly shelved.

Parents who perhaps were in gifted programs themselves as kids and whose own kids do or do not qualify are confused and sometimes outraged at the inconsistent policies about who gets to be called “gifted” and what privileges this “status symbol” can afford someone given this label. But what does it mean to be “gifted”? Should you get your kid tested, and, if they qualify, should you accept services? And will your kid be “better off” in the long run if they’re in a gifted program or identified as gifted when they’re young?

Signs your child may be gifted

In many districts around the country, gifted education is part of the special education program, which doesn’t make it seem like a “status symbol,” but more of an accommodation that needs to be made for students who don’t fit into the average mold of their peers.
