121.) My Gateway Arch sweater. The back features the courthouse, which is directly across the field from the arch and is featured together with the arch on some souvenirs. Made for my trip to St. Louis in June 2018. Hopefully will become a T-shirt someday. #sambarsky #sambarskysweaters #sambarskyknitter #knit #knitting #knitter #art #artist #sweater #intarsia #handknit #gatewayarch #arch #gatewayarchstlouis #gatewayarchstl #archstlouis #archstl #archsaintlouis #stlouis #saintlouis #stl #stlouiscourthouse #yourarch #courthouse (at Gateway Arch) https://www.instagram.com/p/CruQnMdtI0z/?igshid=NGJjMDIxMWI=

I mean, it IS a completely curved arch, so yeah – there are no points #technicallytrue⁠ @gatewayarchnps

8 June 2019 Visiting the Gateway Arch for the first time! I never understood why it was such a big deal until I stood right by the Arch. 630 feet high.

Building bridges with @physicsfun and our Catenary Arch exhibit!⠀ ⠀ Repost: Catenary Arch at Exploratorium: when an arch is built in the shape of this special mathematical curve (even with slippery blocks) the compression forces between each block are always parallel to the curve- the stack is stable with no tendency to buckle. The catenary is the exact shape of a chain hanging by its ends, also known as the hyperbolic cosine. Famously used in architecture, from the buttresses of Notre Dame to the Gateway Arch. 🌟With special thanks to the Exploratorium! ➡️ Follow the link in my profile for more info and where to find many of the amazing items featured here on @physicsfun #exploratorium #catenary #hyperboliccosine #gatewayarch #alysiod #architecture #catenaryarch #uniformload #physics #physicstoy #science #scienceisawesome
