Past achievements and future challenges in the development of three-dimensional photonic metamaterials. We conclude by outlining future challenges for the design, creation and conceptualization of advanced mechanical metamaterials. In this Review, we identify the design principles leading to these properties and discuss, in particular, linear and mechanism-based metamaterials (such as origami-based and kirigami-based metamaterials), metamaterials harnessing instabilities and frustration, and topological metamaterials. These materials exhibit exotic functionalities, such as pattern and shape transformations in response to mechanical forces, unidirectional guiding of motion and waves, and reprogrammable stiffness or dissipation. Originally, the field focused on achieving unusual (zero or negative) values for familiar mechanical parameters, such as density, Poisson's ratio or compressibility, but more recently, new classes of metamaterials - including shape-morphing, topological and nonlinear metamaterials - have emerged. Pre-register for these sessions.Mechanical metamaterials exhibit properties and functionalities that cannot be realized in conventional materials. These sessions will include question and answer periods. With four sessions to choose from, immerse yourself in the story-telling of two First Nations Elders that will speak on their lives growing up as First Nations people and with their experiences in residential schools. Visitors will receive free admission to the Lloydminster Museum + Archives during this time thanks to our generous sponsor, Lloydminster and District Co-op. Admission rates apply for gallery access. The origami butterflies will be assembled to create a kinetic hanging art installation for the foyer of the museum. ![]() In partnership with Arts Without Borders, the 7th annual community art project entitled "Morph, Emerge, Soar" sponsored by Sask Lotteries and Sask Culture, welcomes everyone to drop-in to the Lloydminster Museum + Archives to create an origami butterfly. September 22 - October 14 - Morph, Emerge, Soar Thanks to our partners Lloydminster and District Co-op, Arts Without Borders, Sask Lotteries and Sask Culture. This year, we are offering two unique art and cultural learning opportunities and free admission dates! Culture Days is a national celebration, highlighting the importance of arts and culture in our communities.
