Recreational activities on Crown land

Canadian residents

Camp for free up to 21 days on any one site in a calendar year. This ensures sites are available to others and helps reduce environmental impacts.

Non-residents, 18 years and up

You will need a non-resident camping permit to camp on Crown land north of the French and Mattawa rivers, unless otherwise prohibited.

Camp up to 21 days on any one site in a calendar year.

Check if camping is allowed on the Crown land where you are planning to camp.

You do not need a permit if you:

● rent a camping unit from a person who conducts business in Ontario.

● own property in Ontario.

● carry out duties as part of employment in Canada.

● are a charitable or non-profit group that is authorized by the Ministry of Natural Resources and Forestry(MNRF)to camp.

Buy a camping permit

Non-residents who need a permit can buy one online or through participating ServiceOntario centres and authorized licence issuers in Northern Ontario.

Cost=$9.35+ tax $10.57 (child under 12 without tax) per person, each night.

Fish while camping on Crown land

You need a valid fishing licence before you can fish.

Campfires

Before starting a campfire, check local fire warnings and restrictions in the area. In some cases, camp fires may be prohibited altogether due to seasonal conditions.

The first thing that Valoy saw when she put on color-blind corrective glasses was green — the vibrancy (活力) of the grass and tree — and later, the brilliance of red in stop signs and flowers. Valoy says it’s unbelievable and she has struggled with certain topics, especially the painting class in school and she would even paint the ocean purple before that.

Valoy wasn’t diagnosed with red-green color blindness until the fourth grade. “For the past 17 years, I’ve lived in a ‘black and white movie’,” the recent Louis E. Dieruff High School graduate says. But not anymore. The transformative moment all started with a public speaking class Valoy took. After she made an informative speech about growing up with her color deficiency (缺陷), her teacher, Sandy Kile, was inspired to teach the class a more important life lesson.

Kile made a suggestion that the class should reach out to companies that produced corrective glasses to see if they would donate a pair to Valoy. While Kile encouraged Valoy to write a description of living in a world with mostly shades of grey and brown, her classmates wrote accompanying statements about why she needed the glasses. “I didn’t expect much for that,” Valoy says. “Professor Kile truly believed it was going to happen but we were not sure.”

It wasn’t so surprising when the first company turned down their request. Then, the class received reply from the founder of Pilestone Inc., offering Valoy and six other commumity members his glasses for free. “We started this business by trying to make some difference to people,” founder Ben Zhuang says.

Valoy is grateful to Kile and her classmates for their efforts. But Kile says that she is very glad the students have the chance to realize the significance of lending a hand to those in need, and that being able to aid Valoy in changing her life is something she will never forget the rest of her life.

If you could live forever, would you want to? The challenge of keeping your body alive seems impossible, but some scientists are working on an alternative. They want to create a digital copy of your “self” and keep that copy “alive” long after your physical body has stopped functioning.

In effect, their plan is to clone a person electronically.Unlike ordinary physical clones-which have identical features as their parents, but which are independent organisms, each with a different conscious self-your electronic clone would believe itself to be you.

One plan relies on the development of nanotechnology(纳米技术). Ray Kurzweil, a leading futurist, predicts that within two or three decades we will have tiny transmitters that can be injected into the brain. Once there they would line up alongside neurons and monitor the details of the brain’s activity. They would then be able to transmit that information to receivers inside a special helmet, allowing us to map the brain.

As a further step, Kurzweil foresees using these tiny transmitters to connect you to a world of virtual reality. With the transmitters in place, you could think your way onto the Internet. Instead of seeing pictures on a screen, you would see them in your mind. Rather than send emails to your friends, you could meet them on some virtual tropical beach and exchange messages in “virtual person”.

For a futurist like Ray, this would be heaven, a virtual heaven. Once you upload the brain onto the Internet and log on to that virtual world, your body can be left to decompose(腐烂) while your virtual self can play games for as long as you wish.

However, there is still a problem. To exist on the net, your virtual self will have to live on the computer of a web-hosting company. These companies want to be paid real money, or they will delete your “self” and sell the space to someone else. With your body long gone, how will you pay?

Every year. the Joint Mathomatics Meeting brings more than 5,000 math lovers together. It’s the largest math meeting in the world. In January 2019, mathematicians flew to the meeting in Baltimore, Md., to learn about new ideas and talk about their work. Many even came to admire the latest in mathematical art.

The meeting included an entire art exhibition. Visitors felt amazed at sculptures made from metal, wood and folded paper. One was based on a supersized Rubik’s cube. Many like triangles, were arranged in strange and surprising sizes and colors. The collection also included drawings and paintings inspired by the study of numbers, curves (曲线) and patterns.

Art and math may seem like a strange pairing. People usually experience art through their senses. They see a painting or listen to music. If this art moves them, they will have an emotional response. Working at math problems is usually viewed as something you think about-not feel. But connections between the two fields reach far back in time. Sculptors and architects in some ancient civilizations included numbers and math ideas into their works.

Henry Segerman is a mathematician and artist. When he was in high school, in England, he was good at math and art. But he had to choose. “I went in the math direction back then,” he says. He thought it difficult to succeed as an artist.

Still, Segerman’s math studies led him into the visual areas of math, such as geometry. In 2015, Segerman and some math art friends created a virtual-reality artwork. Participants can put on a pair of VR goggles to float around and through four-dimensional shapes. Art makes it possible to interact (互动) with these shapes, which would be impossible to create in our three-dimensional world. As beautiful as it is to see, Segerman’s work also offers a new view on mathematical ideas.
