Si vous êtes dans un ascenseur et que le câble lâche, n’hésitez pas pour faire une expérience de physique. Ce sera la plus belle et la dernière. Elle montrera l’universalité de la chute libre. C’était un extrait d’une conférence à Liège au B3, en intégralité sur la chaîne YouTube. 📕 Nouveau livre « Comment rester au sec avec une veste mouillée ? » Allary Éditions (Paris).

Why Waves Travel Faster At The Top

A new IV needle design is solving a problem that's existed since the IV was invented. Traditional needles are rigid for the entire duration they're placed in a vein, and since your body is constantly moving, that rigidity causes friction and irritation against the vessel wall over time — especially during long-term treatments. This new flexible needle is engineered to remain stiff only during insertion, then soften once it reaches body temperature inside the vein. That shift allows the needle to

Just because something insulates your body heat from conduction doesn't mean it blocks the long wave infrared radiation coming from it. #ivydoll #Science #thermalcamera #thermalvision #thermalcamouflage
