1. Stroll the Canals. Without a doubt, strolling along the canals is one of the best things to do in Amsterdam. Fanning out from the city center are a series of horseshoe-shaped canals, an area called Grachtengordel. Singel is the first of these canals and was originally the moat that surrounded the main city center. There were officially 1,886 Dutch war brides to Canada, ranking second after British war brides. [4]. Dutch emigration to Canada peaked between 1951 and 1953, when an average of 20,000 people per year made the crossing. This exodus followed the harsh years in Europe as a result of the Second World War. We study gravitational lensing in strong-field limit by a static spherically symmetric black hole in quartic scalar field Horndeski gravity having additional hair parameter q, evading the no-hair theorem.We find an increase in the deflection angle \(\alpha _D\), photon sphere radius \(x_{ps}\), and angular position \(\theta _{\infty }\) that increases more quickly while angular separation s This mapping however is impossible with beyond Horndeski alone, since we find that the theory is invariant under such a transformation. The picture that emerges is that beyond Horndeski is a healthy but isolated theory: combined with Horndeski, it either becomes Horndeski, or likely propagates a ghost.

This article is intended to review the recent developments in the Horndeski theory and its generalization, which provide us with a systematic understanding of scalar-tensor theories of gravity as well as a powerful tool to explore astrophysics and cosmology beyond general relativity.
