When Laws Make Divorce Easier, Women Benefit, Outcomes Improve (2019)
My newly published research shows that both the design of divorce law and how local governments execute it can have profound effects. I used the legalization of divorce to show that pro-homemaker divorce laws increased investments in children’s schooling in married-parent families anywhere from 4% to 6%. The law increased high school enrollment. For an […]
I designed a cube that balances itself on a corner
This cube manages to balance itself on a corner, and can simultaneously rotate around its axis in a controlled manner. It does so using clever controls and a set of three reaction wheels. The original idea for this device comes from researchers at ETH Zürich, who demonstrate their “Cubli” in this video. Its design has […]

What the heck is going on here? SHOP TRIATHLON BIKES What is a non-double-diamond triathlon bike? The tubes […]
Are we visible to advanced alien civilizations?
Abstract:We considered the question of how our artificial constructions are visible to advanced extraterrestrial civilizations. Taking the universality of the laws of physics, we found that the maximum distance where the detection is possible is of the order of $3000$ ly and under certain conditions Type-II advanced alien societies might be able to resolve this […]
Orbital’s Hartnoll brothers look back

Their first single, Chime, entered the Top 20 in 1990. With their crossover fusion of underground and stadium electronic music, Orbital went on to become one of the biggest […]

The more physically […]

This insight reveals patterns and tendencies in password creation, shedding light on common vulnerabilities and the human […]
