Two-tier electoral systems aim to balance regional representation and proportionality. Recently, the mathematical mechanisms of several Northern European two-tier systems have been challenged by increasing political party fragmentation, as evidenced by the expanding German parliament and the majority-deciding disproportionality of Denmark’s 2022 election. Regionality, proportionality, and two-tier systems are defined mathematically and used to identify the common cause behind these developments through the formulation of an impossibility theorem: no electoral system with fixed parliament size can guarantee both proportional and geographic representation. Finally, a new algorithm, geographically ranked guaranteed proportionality, is proposed to circumvent the impossibility theorem.

Le 5 octobre, nous aurons une Assemblée dite nationale, mais vraisemblablement minoritaire chez le peuple!

À peine deux semaines de campagne et déjà une impression étrange. Nous en savons beaucoup sur ce que certains candidats ont écrit, dit ou fait il y a quelques années, mais beaucoup moins sur ce qu’ils proposent de faire au courant des quatre prochaines.

Le mode de scrutin actuel a des conséquences inégalitaires, car le vote d’un grand nombre d’électeurs, quand ce n’est pas la majorité d’entre eux, ne se reflète pas dans la composition du Parlement, déplore l’ex-ministre François Blais.

A reconnaissance satellite suffered an unidentified anomaly and broke apart into pieces. Now, those fragments are trapped in a high altitude above Earth, where they risk a head-on collision with another object. China’s Yaogan-50 (02) satellite launched on March 15, 2026, on board a Long March 6A rocket. The satellite successfully reached its operational orbit—a highly retrograde orbit, meaning that it travels in the opposite direction of Earth’s rotation at an altitude of approximately 590 miles (952 kilometers). A few months into its mission, however, the satellite appears to have malfunctioned. On September 4, the U.S. Space Force cataloged 43 debris objects from the breakup of Yaogan-50 (02), according to Jonathan McDowell, a former astrophysicist at the Harvard-Smithsonian Center for Astrophysics who tracks space activity. ## Pesky debris The satellite’s fragments are currently at an altitude range between 372 and 683 miles (600 and 1,100 km) above Earth’s surface. The pieces remained within the satellite’s distinctive 142-degree inclination orbit. At that altitude, the resulting debris will likely stay in orbit for a long time. Debris that’s left in orbit below 372 miles (600 km) normally falls back to Earth within a few years due to atmospheric drag. The higher the altitude, however, the longer the debris will remain in Earth orbit. For debris that’s orbiting at an altitude of 500 miles (800 km), orbital decay can take centuries, according to NASA. Above 620 miles (1,000 km), the debris can keep circling Earth for thousands of years. There, the fragmented junk risks collision with other spacecraft or orbital debris, which would result in the creation of another debris field. ## Tough break The European Space Agency estimates that there have been more than 660 explosions, collisions, or anomalous events resulting in fragmentation. As it stands, there are currently more than 1.5 million space debris objects in Earth orbit. It’s not clear what may have caused the Yaogan-50 (02) satellite to break apart, but it may have been a propulsion or battery failure, or it may have itself collided with another object or space debris. The Yaogan-50 is a series of remote-sensing and reconnaissance satellites that China claims is designated for national land surveys, crop yield estimation, and disaster prevention and mitigation. There is speculation, however, that the satellites are used for intelligence and military surveillance, according to SpaceNews.
